This depends a lot more on what you plan on doing once the OS boots. I accidentally loaded Win11 on an HDD (disk 0 was HDD, not SSD) for a few hours. It was noticeably slow, but it ran my diagnostics utilities well enough.

If you’re using it for light web browsing, basic office software, etc, then it might be fine.

But something else caught my attention - you inquired about “restoring” it at shops, meaning you intend to pay money. SSD and RAM are obviously what anyone would upgrade, and you’re balking at it. More to the point, you expect to run Linux, but didn’t even install it as-is to test it out?

There’s some missing context here. Also, 2gb laptops haven’t been a thing in a very long time. You might very well get a better deal by just buying a used newer model that already has what you’re looking for.
