so i wanted to put windows 7 instead windows 8 on my Acer e3 111:
i entered BIOS - changed UEFI to Legacy - cause UEFI didnt saw my USB flash with windows 7 on it!
started Installing windows 7 and when i got to the partition part, i formated all the partitions (which probably was a mistake):
ONLY THEN i noticed that all partitions are in GPT and windows wont install on them, so i decided to change them to MBR through prompt (CMD): diskpart → list disk → select disk 1 (1 signifies the number of GPT disk) → clean → convert MBR.
and so it did, only after restarting - it gives me: no bootable device - insert boot disk and press any key
it sees the USB flash in bios boot mode or in F12 boot menu but does nothing!
