It came with Windows 8.1 installed, and I wanted to rollback to Windows 7. Before realizing I should've converted the disk from GPT to MBR, I tried a "custom install" of windows 7, and started formatting partitions. When the install didn't go through (due to the fact it's GPT, not MBR) it left me with a useless laptop. It can't restore to factory settings, and I have no disk.
Wish i converted it to MBR first before formatting partitions...but, any help?
