Hello to all,
The message cpuid=rdseed32 appears during booting;
it's not possible to boot Ubuntu 26.04 beta Live USB!
On another machine with Win 11 i can boot from stick.
i'v tried some solutions, but nothing helped.
At this time no new Bios is available.
Any other solution?
What Tool did You use the create the Bootstick? Did You checked the Checksum of the Ubuntu ISO?
I used Balena etcher and also the internal Imagewriter an yes, i checked the Checksum and it matched.
Etcher can be a bit ... meh. If you have a windows Machine, I can recommend Rufus. There You can actively choose between GPT or MBR for UEFI BIOS or Legacy BIOS.
On Linux the only Program I know what offers that would be Ventoy. If You know that Your BIOS is in UEFI Mode, I could also recommend Impression or the Fedora Media Writer.
Another Thing: Are Secure Boot and Fast Boot in BIOS disabled?
I used Rufus on Windows, Secure Boot and Fast Boot disabled, nothing happend.
I've tried this:
I installed ubuntu 24.04 next to Zorin OS as Dual Boot; after that i upgraded to 26.04 Beta.
The same result, but i could change during the Advanced Option the older Kernel from 24.04 (6.17.0-20-generic) and: tada, 26.04 still booting!!!
The new 7.0.0-10 Kernel in Ubuntu 26.04 is the root cause not booting on my machine because the cpuid=rdseed32 trouble.
Tomorrow i trie to install the last amd microcode package for 26.04 and check again the new kernel.

The latest amd microcode package was already installed;
so i think i must wait for a new Biosor an optimized 7.0.0-X Kernel...
