Hello and sorry for my bad english.
I have an acer aspire switch 10 with Windows 8 but one day, i can't boot it, i have a windows error. i can't go to the widows recovery menu i have the same error. so i have make a widows 10 usb key and i disable secure boot from the bios. the pc start on the usb key, windows 10 boot and after that i have a black screen. So i try to make a windows 8 usb key and that time that work, i can go to the installation menu. but when i want to delete or erase a partition that won't work. and if i try to install directly widows in the main partition, the installation start and i have an error.
I try to use Gparted to erase partition but that won't work
very sorry for my bad english
