What to do if the laptop says checking media. When you turn on the computer, “Checking media presence” appears. Why is downloading from the network activated?

Question: Messages ">>Checking media presence >>media present..... >>start PXE over IPx4." while loading

How to remove this before booting your PC:
>>Checking media presence....
>>media present.....
>>start PXE over IPx4.

Answer: disable network boot in bios. (first boot device should be HDD)

Good day.
Build a new computer
i5 7500
gtx 1060 6gb
8gb ram
new 600 watt power supply
msi 250
, I left the old tin, like a seagate 7200 500gb

I installed win 10 pro and got a strange effect.
1) the computer takes a long time to turn on (a minute or a minute and a half)
2) after turning on the computer, for about 10 minutes - 100% disk load and small brakes in addition with huge noise from this very disk, in the task manager not a single program loads more than 10-20 MB, while the load is indicated as 100% (before the dance with a tambourine and disabling all services, rechecking chkdsc /f /r, which took countless hours, and the effect of fragmentation was 30-40 minutes after switching on) that is, after some time the load drops completely, to 0-5%
Question: how to remove 100% disk load after switching on?
Thank you in advance!

Answer: Personally, I would start by finding out whether the hard drive is loading because the system is simply being updated. And if this is so, then I would decide what is more important for me: update or speed.

Well, I would replace the cable, they already wrote that to you.

Question: How can I remove the boot disk selection during startup?

Out of the blue, a prompt appeared asking me to select a boot disk when starting the PC. I don’t understand how this happened, and most importantly, I can’t remove this message. Everything works as before, but during startup it hangs until you press Enter. In the BIOS I set my settings and default settings - it doesn’t help. Can anyone tell me how to get rid of this?
Good afternoon, dear forum members.
Help solve the problem of loading the Catalyst 4503 processor. Periodically, the processor loads up to 50-60%. Below is the show version and two screenshots.

From the screenshot you can see that the processor is loading the Cat4k Mgmt LoPri process. Is it possible to correct this situation?
Basically the processes K2 Packet Memory Dia and K2AclCamMan Audit re download. What are they responsible for and how can the situation be corrected?
Thank you in advance for your help.

Answer: Well, actually, you can try the options for K2AclCamMan Audit re which are offered in these docks:
according to the 1st link it is to change the TCAM algorithm to scattered
on the 2nd link, there is a list of sequential actions (Solution section), provided that you have the error %C4K_L2MAN-5-ROUTERMACADDRESSRXASSOURCE:Packet received with my own MAC address () as source on port in vlan error message in your logs.

On my own behalf, I’ll add that if the problem is in K2AclCamMan Audit re (and this is TCAM, QOS, security), then it’s better to clean up the config, remove/optimize ACLs, review QOS policies, look for internal loops, and loops in general, perhaps there are hosts with the same poppies or the MAC address table is overflowing. There are a lot of options here, they can be both software and hardware. And of course, update the software to the latest recommended for your hypervisor.

Question: Windows 7 does not start after changing the motherboard (STOP 7b error, booting from disk or flash drive does not work)

Good afternoon. I can’t even reinstall Windows - it throws me to the standard recovery window, which doesn’t help either.
I changed the MSI 7673 from the mainland to ASUS H170M-PLUS, changed the RAM from DDR3 to DDR4, and also changed the percentage. on I5-6500 OEM. There is only the ability to enter the BIOS (it sees both the DVD drive and the hard drive). Please tell me how to solve the problem?

Answer: Most likely the mode is uefi and the bootable flash drive should also have uefi.
There should also be a fast boot mode; it most often skips all connected devices to speed up loading.
its off
or turn off this mode and install a regular axis.

Question: Black screen on boot

Hello! This is a problem with a laptop - I bought an Acer Aspire ES1-512 a week ago. After normal use for a week, today I started it up and the ACER (logo) window pops up, just a gray window with a mouse cursor. It doesn’t respond to any key combinations. I tried to make it in time. press F8-10 and catch the selection of the old successful launch of Windows, but it doesn’t work. I can first go into Bios (F1-2). I tried:
1) In boot mode there is a parameter uefi, you need to switch it to legacy (I read it on the Internet). Below are 5 photos of what strange entries began to appear after loading
2) The priority is the Hard drive (the only one)
3) Reset BIOS settings to default
Probably as a last resort, I think it will be possible to reinstall the system if the BIOS opens. But suddenly I need to restore it like that. It’s worth the licensed WIN 8.1 that came with the laptop right away.
Please tell me what could be the problem?

Question: When the computer boots, the message appears (see photo) ddr at rows 0 1 2 3

Good afternoon
.
Before Windows starts loading for me, all sorts of parameters and numbers flash on the monitor.
And now the computer stops on a certain screen, and on a certain line on which it says ddr at rows 0 1 2 3 and the cursor under 3 blinks.
The situation occurred after I tried to restore Windows and used the CHKDSK command there. It lasted a very long time. The program finds and corrects errors.

So, after looking up the problem on the Internet, I took out the BIOS battery and put it back.
It worked once.
Then it wouldn't turn on again. Then it didn't help.
It stayed for a month. Turned on. Then again. Then no.
Then I tore out half of the cords in the system unit and inserted them back. Turned on then no.
Now I'm tired of it. I'm writing here

Answer: My opinion is that this line has nothing to do with it...
And it's ALL about the hard drive and the Microsoft bootloader, which freezes the download... Due to a logical error in partitioning the hard drive, an endless loading cycle results.

Dealing with this is quite simple. You need to launch MHDD and run the console command CLRMBR
After this, you can start testing the hard drive and recovering data...

Question: Gigabyte GA-Z87-D3HP black screen on boot

Good day. This situation is strange. When I reboot the computer, I have a black screen, the monitor blinks, as if in standby mode, and as if there is no video signal being supplied to it... the monitor lights up when I need to enter a password to log in to the system (Windows 8 is installed) ). Accordingly, I can’t get into the BIOS, nor can I see all the motherboard’s screensavers when loading... what could be the problem? Thank you.

Answer: plywoods, in BIOS select built-in. video if the cable is connected to the mat. board, or discrete VC, if the cable is included in the discrete

Message from plywoods

costs Windows 8

Windows 8 should still work in UEFI mode if the very fast boot mode is enabled in the BIOS, in which you cannot get into the BIOS when you turn on the computer and the BIOS will not display anything on the screen at all! You need a utility from mat. boards, the bark works from under a running system and there is a function something like Reboot and enter BIOS. And then in the BIOS, disable the very fast boot mode

When operating system errors occur, they are, in most cases, relatively easy to resolve. As a last resort, you can always reinstall the distribution, which will lead to a complete healing of the computer (if the problem is software). It’s another matter when the user encounters problems at the hardware level and with programs that ensure the operation and interaction of the equipment. One of these, for example, is the error EFI Network 0 for IPv4 boot failed no one will be able to figure out what to do with it without turning to the appropriate information sources.

What is this error EFI Network 0 for IPv4 boot failed on Lenovo laptops

« Error: EFI Network 0 for IPv4 boot failed" is a system message in which the user is informed that an attempt to boot over the network using the fourth version of IP protocol failed. Actually, this is not surprising, since ordinary PC users boot from a hard drive, and those who spared no expense in purchasing a solid-state drive boot from an SSD.

This message can only be seen by owners of Lenovo laptops, since on other computers it calls it a little differently.

The corresponding error may appear for many reasons, for example, as a result of flashing the BIOS or careless work by the user in the corresponding “engineering menu”.

What and how to do to fix the EFI Network 0 for IPv4 boot failed error

There are several options here. First, Lenovo laptop owners should try resetting the BIOS settings to default. This is done like this:

1. Turn on the laptop;
2. Wait for the start boot screen (not the OS, but the computer (usually it shows the Lenovo logo);
3. Hold down the Fn+F2 keys for a second.

On a number of Lenovo laptops, pressing these two keys simultaneously will reset the BIOS settings. If this happens, then after the next reboot the operating system will begin to load.

If the appropriate actions do not lead to the desired result, you should do the following:

1. Turn on the laptop;
2. On the start boot screen, press F2 or Del (depending on the laptop model);
3. In the “engineering menu” that opens, go to the “Boot” tab;
4. Select “Boot Mode” and press Enter;
5. Select “Legacy” from the list that appears;
6. Go to the “Exit” tab;
7. Select "Save and reboot".

After the laptop reboots, the operating system should start loading, and the “EFI: Network 0 for IPv4 boot failed” error should no longer bother you.

If these actions did not lead to the desired result, then in the BIOS you will also need to find the “1st boot device” item, which you will need to expand and select HDD + (name of the hard drive). This will tell the computer which device it should boot from first. Therefore, it will stop trying to boot from a network in which the user, for obvious reasons, does not have a bootloader and system.

It should be noted that items and tabs in the BIOS may have different names (this depends on the computer model).

In contact with

"Start PXE IPv6/IPv4. Click to exit."Is the message black screen which occurs mainly on laptop VE ( DELL, Toshiba, Lenovo, ACER, Asus), but sometimes PCs are not exempt from this.

Taken by many as an error message Windows 7, Windows 8, Windows 8.1 or Windows 10"Start PXE IPv6/IPv4"Is it really Announcement who has not the slightest contact OS This happens almost immediately after a reboot or after the computer is turned on.

What does PXE mean?

PXE They are the initial Pre-Execution Environment, In the language of IT he reads " fairy"And they represent loading method/ Booting the computer from painting from internal network (LAN). To be precise, using PXE boot laptop can or PC image a OS,The condition is that this image will be stored on LAN Hard disk On older systems this option is also called or.

How can we run PXE over IPv6/IPv4 and run the operating system.

Usually, BIOS laptop PDA or PC is installed in this way, list download priorities(Order of boot devices or Boot priority option) Either: CD/DVD, HDD, or PXE Due to changes in the BIOS, it is likely to install and when starting up, your laptop is waiting for an image or network/internet operating system to load. To change the boot order you will need to go into the BIOS and search for " Download priority". To access the BIOS you must first Turn off your computer everything(Laptops Off "Cold" is tintand power button for a few seconds. 10-15 seconds). after launch Reptiles key press F2, F12, F8, Del or Esc, This key may change depending on laptop model For example, vault your laptops Toshiba key to access BIOS is F2 and the menu key directly enter F12 Download priority where you can choose the boot order, without having to enter the BIOS.

Once inside the BIOS and arrived at Boot Priority Menu, Select the first block HDD/SSD or CD/DVD If you want to install the operating system on DVD in the future. Once you have made these changes in order to upload, press F10 To save changes and restart your computer. If you installed as first boot HDD or SSD Then it will download automatically after launch Windows The PDA is installed on your system.

If you boot the system from the HDD or SSD first and the message Start PXE IPv6/IPv4 appears again at startup, signs for concern. Regardless of the operating system has a serious problem and cannot be restarted. In this situation it is mandatory to repair the system Windows DVD installation, or worse... HDD The PDA or SSD has a problem and cannot be read. or try reinstalling the operating system DVD/USB Flash and check if the hard drive is visible installation or use Live Linux system or Live Windows(through Hiren for example) in which check the status of the hard drive Achievements on your laptop/PC.

Start PXE IPv6/IPv4. Click to exit.

For some users of personal computers and laptops, when turned on, even before the operating system starts, the message “Checking media presence” is displayed on the screen in the form of an inscription in white letters on a black background. This is usually followed by the message “Media present...” and then “start pxe over ipv6 (ipv4)”.

In this article we will tell you what this means and how to get rid of these messages.

What does it mean?

This group of messages when you turn on the PC indicates that it is currently trying. The thing is that in addition to standard booting from local media, be it a hard drive, optical drive or flash drive, there is booting from the local network. Most often it is used by large organizations when it is necessary to create a unified information system. In this case, there are simply no hard drives on client computers, and the operating system and all working tools are stored centrally on the main server.

When the network boot starts, the computer screen looks something like this:

Start downloading from the network

Why is downloading from the network activated?

If everything loaded fine for you before and the phrase “Checking media presence” was not there when you turned it on, but at some point it appeared without you specifically turning it on, then there are several reasons for this.

The second option is problems with the hard drive or system bootloader. Even if the desired hard drive is first in the boot queue, and the PXE boot or Wake on lan option is activated, then if it is not possible to boot from the system partition, the queue will proceed to attempt to start from the network, as indicated by the message described above.

How to remove “Checking media presence”?

There are several options. The first and easiest is to check the boot priority in the BIOS, setting the hard drive to first place. It is also worth finding the PXE boot and Wake on lan options and disabling them by moving them to the Disabled position.

Disable network downloads

Setting the highest boot priority to the hard drive in the BOOT partition

If after this the problem does not go away and the phrase “Checking media presence” is still displayed, preventing the operating system from loading, then most likely you have problems with the system partition.

In the best case, the hard drive is simply disconnected or the bootloader has been removed from the system partition. In this case, check that the cables between the hard drive and the motherboard are securely connected. On a laptop, just check that the hard drive is securely installed in the connector.
