Boot Windows 11 using legacy BIOS on PCIe M.2 SSD | Arch Linux Community | Page 1

TLDR: How do I make Windows 11 boot from a system that only supports BIOS legacy boot and is unable to boot from my PCIe M.2 SSD expansion card?

GRUB doesn't detect my PCIe M.2 SSD.
When I "ls" in the GRUB shell I only see the USB drive. (Screenshot)
Does anyone have an idea on how to get this working? nekoThink

if it cant boot from your m.2, install a different storage device

#

or a different bios, if you're lucky your system supports coreboot which can be built against UEFI

#

and, for me at least, using coreboot lets me boot from storage devices not supported previously (microsd cards)

I can only use SFF SAS drives. Which are too expensive for the performance/capacity I would get. (Compared to a PCIe M.2 SDD.)

sas is just slightly weird sata, theres probably a dongle somewhere

#

or you can use a usb to sata dongle
