Hai. So my friend got me to get linux ubuntu, and i like it but I want windows 10 back and it seems ive tried everything it got rid of it. If anyone can help me please and i got the installion on a usb but when i go to do it is say missing a perition disk. Please help...
This is likely due to the fact the drive is formatted in a Linux file system (like EXT4)
You would have to completely remove any non-windows partitions on the drive before windows will let you install. (or at least have 1 accessible FAT32 or NTFS partitions with enough space for the windows setup files)
I suggest a Linux Live disk (like the ubuntu installer) use gparted, remove any partitions on the drive and win10 setup should just see a drive with 100% unallocated space and create whatever partitions it needs.
