I had to pay to have Windows 10 reinstalled. > Apart from other answers to this, anything with Win10 originally installed (and you don't say this, it might be an upgrade, perhaps from Vista) will have a recovery partition which can be triggered from a key during boot. OK, it completely nukes the original installation, returning the computer to factory-issued, but it costs nothing. Another point: buster will install dual-boot to a UEFI Win10, but on my netbook, will not dual-boot afterwards. It may still be possible to dual-boot using the startup boot menu key, not GRUB, though it isn't on my machine. -- Joe
