Question Second OS wont boot

[ZombieLover97]

Hello everyone,

I have a small issue with booting to a new SSD. I have an 250GB Samsung 860 evo and I got a 128GB Intenso SSD just for linux. My plan is to have the good drive with windows 10 and the small with one distro of linux. I installed Q4OS Gemini on my 128GB. My bios though can't detect the second drive as bootable in UEFI mode, only in CSM but when I change to CSM and disable(or enable) fast boot I can't go to bios.
Please help !!!

Have you tried the Linux drive on it's own?

 

[ZombieLover97]

Yes. It does't see the linux drive as bootable unless I use CSM

 

[Johnwmel]

Some bios have dual UEFI/ CSM or CSM/legacy

"fast boot I can't go to bios"
Secure boot should also be disabled.

Move your Linux from legacy BIOS to UEFI in place with minimal downtime

This article describes a complete procedure for moving to UEFI.

so is it safe to enable csm in mine (MSI MPG Z490)?

It has CSM/UEFI and I gotta choose between them

I installed Q4OS oin my Samsung ssd with windows and just use the other one for Adobe suite and Matlab (the programs I use often)
