BSOD upon repair mode, UBS boot disk created but no repair option

Hi all - my laptop refuses to boot and when I start in repair mode I get the BSOD with just the cursor visible and nothing happens.

If I reboot in safe mode then it hangs at windows\system\drivers\bootdefragdriver.sys

I have researched and believe this driver is linked to Glarys Utilities, but am obviously unable to uninstall the program or driver because I can't boot into Windows.

I therefore downloaded an ISO file and created a USB boot disk (as per one of your tutorials) with the intention of rebooting into repair mode, but when I boot from the USB and press F8, there is no repair mode option. All it does it try to reinstall windows from scratch, which I am reluctant to do.

Does anybody have any suggestions of how I can either delete the bad driver (if that is indeed the problem) or how I can still get into repair mode from the USB drive?

Many thanks

Hi - I've now tried that and upon booting from the USB, it starts to load Peppermint setup but then the screen goes completely black and nothing else happens.

Furthermore, if I then try and boot from the hard drive again, I just get a flashing white cursor in the top left of a black screen and it hangs indefinitely. I can't even use the F8 menu anymore to try safe mode etc.

Have you got any other ideas? I really hope I haven't lost all my data permanently.

Thanks
