Bullseye RC2 Installation disk boots to grub shell

[EJMRoberge]

I would like to install Debian Bullseye RC 2 alongside my Windows 10 and Ubuntu.

Using those two images :

• debian-bullseye-DI-rc2-amd64-DVD-1.iso

• debian-live-blsy-DI-rc2-amd64-kde+nonfree.iso

And as stated in the title, I tried with both secure boot enabled/disabled, I boot straight to a Grub command shell with a message to press TAB to see commands and options.

I have no idea what causes this.

I just tried on a different machine and the live session booted correctly. I believe this is related to my laptop security feature.

EDIT: I used a different sequence. With secure boot disable, I powered on the Asus laptop and presssed ESC to access the boot menu. Now I could see the Partition 1 from the USB drive and booted from it to a very basic blue Grub. After slecting any of the options I get this error message :

error: Unkwon TPM error.
error: Unkown TPM error.
error: you need to load the kernel first.

Press any key to continue...

I just found out there is a bug filed for this issue : https://bugs.debian.org/cgi-bin/bugrepo ... bug=940911

The work around is to type (e) in grub and add

Code: Select all

rmmod tpm

before the 1st insmod. I am typing this in the live session.

So, not solved, but there is a workaround.

So now that Debian is installed, I end up with a similar problem, but this time I cannot reach the grub entries. Now I would need to manually add :

Code: Select all

rmmod tpm

to grub to workaround the tpm issue with testing images.

I simply don't know where to put it.

Can't you type it in the GRUB shell ?
