Edit: holy shit, I did it! The install media is booting off a little SSD partition! It was ultimately quite simple. Will update with instructions once done, for posterity.

This is a weird one. My partner was gifted a Surface Go model 1824 (gen 1) by their best friend, who unexpectedly died a couple of weeks back. It’s nearing the Windows 10 end of support date, so my plan was to install Mint, but there’s a hitch: the only goddamned USB port on the system is shot. It’s the USB controller, which I’ve given up on trying to fix as it looks like a hardware issue.

I still want to install Linux because this thing now has super sentimental value. I’ve freed up 16 gb on the SSD, so I have some space to work with. There’s a micro SD slot that still functions, but the stupid system doesn’t support booting from it (although a Reddit post suggested you can still do so if you set it up in Grub, which I don’t know how to do properly at all). The only thing I can think of is installing something on a partition or partitions that acts as install media, but I have no idea how to do that.

Ive tried using Grub2Win’s ISOboot function with the Mint install ISO and I can get it to start, but it stalls out waiting ad nauseum for DHCP. I think it thinks it’s a PXE install. Maybe my parameters are set wrong? Actual PXE is a no-go because no network adapter. I tried intently staring at the Mint ISO, then staring at the tablet; no data was transferred, but I did develop a headache.

I’m so, so stumped. Any ideas, anyone?
