Ubuntu, as always, is very risky to set up. I believe I selected the option "erase disk" on the USB. It never mentioned Windows, like it did the first time I installed it, earlier tonight. I thought it was referring to the USB itself with a sort of misnomer, and went ahead with that. Now i can't boot Windows 10. Is it really gone? Is there any way I can recover enough memory to boot Windows 10 again?
I tried TestDisk, recovering the disks as best I could, but I still couldn't boot.
I really have to be less careless. I'm not this stupid, just really careless.
Thanks.
