Getting 2 Dual boot?

[daanheuvelbeuk]

Recently I got myself a superfast configured Windows 11 gaming system. I thought to build in my Ubuntu hard drive and continue with dual booting. But alas, my "MSI Click BIOS 5" is configured to 'fast boot'. And I do not have a way to configure a boot delay, or even to show the Boot window all the time. So now I have problems accessing my Ubuntu distribution.

At the moment I have installed 'Oracle VM VirtualBox' where I can boot Ubuntu. But I cannot access my Ubuntu drive, as VirtualBox uses Windows Explorer to look for drives, and Windows is unable to see EXT formatted drives.

I installed "Windows Subsystem for Linux", have no idea what drive it uses, tried lsblk and got the following output:

thor@Odin:~$ lsblk
NAME MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda    8:0    0   256G  0 disk
sdb    8:16   0 339.8M  1 disk
sdc    8:32   0   256G  0 disk /

So, anyone know what I can do?

This is probably a UEFI setting?
Can you not access the UEFI settings and disable it?
