TL; DR: How to fix EFI partitions that accidently deleted and cause windows 7 gone from dual boot
What happend: So recently im dualbooting windows 7 with linux zorin os (based on ubuntu) and tried to reinstall linux but accidentally deleting the EFI partitions and now only linux show up on grub, i can't boot to windows
Before Accident: Windows 7 dualbooted with zorin os, when installing zorin it prompted me to make EFI partitions thinking its just for zorin
What did i do:
- Plug linux bootable usb
- Readding (delete and add back) Swap, Root, Home, and EFI partitions
- Error: Can't install, Fatal Error
- Grub Rescue Showed up
- Boot to zorin live sessions
- Run "Repair Boot"
- Repair boot ask to do some command on terminal
- Restart the device
Result: Windows Partitions is Intact but can't Boot from grub because memorytest and windows 7 is gone
