Arch install sets up as sda instead of sdb

Installing Arch 2021.09.01 from USB in UEFI mode.

Arch detects the SSD on my HP Pavilion x360 as sdb, and the USB install device as sda. I was able to get Arch installed on sdb but as I suspected, after the install, it won't boot.

I checked the laptop compatability chart on the Arch site but the x360 isn't listed.

After the install, I thought I could change the drives in fstab, but Arch uses GUIDs so I'm not sure where the GUID-to-block device mapping is done at.

Can someone tell me if it's possible to either change files on the installed Arch (sdb), or if there is a way to reinstall, reordering the drives so my SSD is listed as sda?

Thanks

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

If your problem is solved please add [Solved] to the title. If not you may have a look in /etc/fstab and make sure that your partitions are not identified by their path in /dev/sdx# you can use uuids instead as proposed in the  Installation guide
