I had dual boot for both win 7 and Ubuntu 18.0 .. I decided to delete Ubuntu so I logged in win 7 and used dsk management tool to delete Ubuntu root and swap partitions. After this I restarted pc to find an error about grub.



What made it worst that I tried to fix it by going into bios setting (F2) and reseted to default settings



Now it can't boot into hdd or even bootable usb sticks trying to install win 7 or 8 .



"No bootable device insert boot disk and press any key"



I even backed up all of my data and formatted the whole hdd to make sure that everything is clean. And still it is not booting into hdd or bootable usb.



Please note : only Ubuntu installion sub bootable stick can boot with no problem
