Windows 10 or rather Windows 7 for this old notebook?

On the manufacturer's website you will only find drivers for Windows 7 for the notebook.

It is a TravelMate 7730. It is only a little dusty, but otherwise in very good condition.

If necessary, Linux?

I would definitely stay away from Win7!

Linux… That's another thing with the drivers. Rather not.

I would still advise against Win7.

Win10

I recently got on an old HP-G7

Installed Win 10 that went off like Schmidt's cat…

Unless unusual devices are installed, Win 10 has all drivers on board.

How much ram and what CPU is in it exactly? Under 4GB you don't even have to start and 8GB are recommended for Win10. If necessary, an SSD in if not yet in it. Then it could be something with Win10.

For your orientation: I have an 8 year old laptop that is now running well with Win10. After the release, it was a thing with Win10 (the free upgrade was done directly), because not everything was supported yet and I had significant problems. With the current version of Win10 it works great. But also has 8GB Ram, an SSD and an I5-2450M, and a GT555M…
