Can’t get back my windows or install windows after installing arch linux

If your windows supports MBR only and you have used cgdisk to partition in linux it wouldn’t work (should use cfdisk to preserve MBR)
to get back your windows you should convert your disk back to MBR to do that
insert windows live cd /installation and press Shift + F10
or go to command prompt

first get partition recovery software from
http://www.cgsecurity.org/wiki/TestDisk

you can use it in dos/command prompt

in command prompt type

diskpart
list disk
select disk 0
clean

it will erase all your hard drive partitions but not permanently

now use testDisk to search for your lost partitions
and simply rewrite/recover them

that’s it folks
