BSOD while trying to uninstall Comodo Internet Security (0x1000007e)

Let us know if there are any other problems.

I've finally got around to doing this. I'm currently running SeaTools Long Generic on the E drive.

SeaTools Short Generic on both drives passed, and Long Generic on the C drive passed.

Long generic failed on the E drive. Test code 6C9AC2A4. The hard drive is not under warranty; I'll replace it soon. I'm running the checkdisk now.

I'm trying to boot from DVD to get to memtest86+. Windows won't let me (the "use a device" option isn't listed when I shift+click restart). Screenshots of the advanced options screen and UEFI firmware settings are here. How do I boot from DVD?

See if these links help:
Access BIOS Change Boot Order for Any Version of Windows

Change the Boot Order to Boot from USB or DVD on BIOS / UEFI | PCsteps.com

The only option for Boot Option #1 is the Windows Boot Manager; and I can't figure out how to add another UEFI Boot Option. I don't think those links would work

Chkdsk log for drive E at chkdsk-e (2) - Pastebin.com. It seems that there are some bad clusters, some were replaced. An unspecified error occured (75736e6a726e6c2e 4fa).
Chkdsk log for drive C at https://pastebin.com/Nd3vE9v7. This one says that no problems were found.

On the e drive please run these administrative command prompt commands and post the results:
1) chkdsk (this command should complete rapidly)
2) chkdsk /scan (this command should complete rapidly)

3) When these have completed > right click on the top bar or title bar of the administrative command prompt box > left click on edit then select all > right click on the top bar again > left click on edit then copy > paste into the thread

4) chkdsk /x /f (this command may take many hours to complete)
5) chkdsk /x /f /r (this command may take many hours to complete)
This will repeat the prior command to see whether it will produce the same or different result.

Have you had any bluescreens yet? If no and if you still need support with other problems, you can create a new thread in another forum area. There are experts who will help you too. Windows 10 Forums - Windows 10 Forums
Thank you

Nice progress. You were able to complete the tests/repairs without the error.
The drive is fragile and had corruption and bad clusters.
The chkdsk inability to read only + the increased bad clusters + the sea tools fail all together suggest an immediate drive replacement. The unexpected could happen in 6 months or next week (for example failure to boot) so make sure all important files are satisfactorily backed up.
