I bought my notebook last year, when I was still resident in Taipei.
ASUS TUF GAMING F15 with 64 GB RAM and 2x 2TB M.2 SSD.
Windows 10 was installed on the first M.2 and the second M.2 was prepared for Ubuntu
I moved to Vienna, Austria and had a hardware failure. I had to send the machine TWICE to Czech Republic for Warranty repair. The hardware was fixed, but they refuse to set up the two M.2 as it was. They combined it to ONE large drive of 4TB. With this I could not install Ubuntu anymore.
So far it seemed ok.
BTW, the BIOS version is 315
The BIOS shows Storage:
PCIE RAID Voume 1
Device Type: NVMe
Model Name: Intel ASUS_OS
How can I fix this machine finally.
PS: I will never buy an ASUS machine again to use in Europe!!!
Since fast boot skips some BIOS checks and tests, it may not detect some hardware changes or updates, such as new drives, cards, or peripherals. This can lead to errors, conflicts, or missing drivers. Fast boot may also interfere with some encryption, security, or backup software that require full access to the system during the boot process. Fast boot can also make it harder to access the BIOS settings or boot from other devices, such as a USB drive or a CD.
If necessary you could also try disabling fast startup in windows
