Swapping Windows 7 disk breaks Suse boot disk

[ratzi]

Hi Mark,

@heseltine

Here is a screenshot of a Windows 7 disk management screen that is similar to my machine:

I saw it.
Still, when I once installed windows 7 in UEFI mode I got a 3rd small partition, called ‘system reserved’ (or sth. similar) with a size of 130 MB.
That 3rd partition is missing on the page/screenshot you linked from the web.

@heseltine

Both my Suse disk and the windows 7 disk are therefore booting EUFI.

If you want to make that sure, plug the windows 7 disk, but boot from a recent Linux live CD,
open a terminal, say ‘su -’ to become root, then say ‘parted -l’, copy the output to a file, and post it here.

Please do it, as well to confirm the setup with respect to partitions.

@heseltine

The secure boot option in BIOS appears to be either (1) Windows mode EUFI or (2) other OS. The ‘other OS’ option appears to switch off secure boot in the BIOS (EUFI).

Hopefully.

@heseltine

There must be some sort of communication between a disk and BIOS.

The hard disk just can not communicate on that level.
It’s the BIOS / UEFI firmware that does the job.
And apparently the BIOS doesn’t handle your openSUSE disk in the same way as your windows disk.

Good luck
Mike
