Can't boot computer, can't access safe mode, hangs on aswrvrt.sys

[inktrashing]

Restarted OTLPE and ran chkdsk, which returned results. But running FRST, even taken from the flash drive onto the OTLPE desktop, gave the same report as already attached, and running chkdsk after that would give the same "Cannot open volume" error.

Am I running FRST wrong?

There is a glitch sometimes because OTLPE is based on Windows XP, and your system is Windows 7...

Do you have Windows 7 installation disk, so you can try to boot and access recovery console via disk?

Unfortunately, no, my computer only came with a separate partition if I want to reinstall Windows ...

Should I attempt running the Windows .iso from my flash drive again?

You can download trial version of Windows 7 from here, burn it to the cd or USB (using Rufus) and then access recovery console

Burnt that version of Windows 7 to a flash drive with Rufus, but attempting to boot from it loads the Windows files, shows the Windows startup logo and then freezes on a black screen.

Are you sure you burned it correctly, and that you selected USB to boot, because there should not freeze this way?
