Knoppix Doesn't Boot On Windows 8.1

[Threshold]

So I have finally managed to disable UEFI and get the option to boot from a dvd.

Unfortunately whatever I try to boot from (Knoppix, Ubuntu, Xubuntu) stops halfway.

The screen resolution changes constantly and the monitor loses the signal several times and than I only get some garbled colours like when you try to play an encrypted video or just a black screen.


For Knoppix I get the "loading sequence" announcement and the splash screen with the penguin but than it stops there.

Any idea what causes this?

Thank you.

Have you done testdvd and checksum tests on the dvd?

Hi utu,

Do you mean testing the knoppix image after downloading it?
I did the md5 test and it completed successfully.

Anyway i loaded all these images into Virtualbox and they work fine so i guess they are all right.
Unfortunately i don't know if it's possible to access my ext3 usb drive from Knoppix, loaded into Virtualbox, and if so how to do it.

Anyway i'd like to be able to have a functioning copy of Knoppix in case I run into any PC issues as it has saved me in the past many times.

Thank you.

I've had a similar problem with the video display, and have sometimes been able to resolve it by setting the screen resolution at boot time as per the help pages suggestions accessed with f2 and f3
