Uninstalled Fedora Now Windows Is Not Booting

Hey folks, I'm out of my depth and really need some assistance. I tried to install Fedora from a USB stick on a partition I created in windows. The machine had Windows 10 installed. The Fedora installer worked fine, but there was no boot option when I restarted. I tried to install again, same result. Everything said it was fine, but no boot option.

I'll have to do more research, I thought, so I went into Wibdows, deleted the Partition I'd installed Linux on and merged it back into my main drive. Now windows won't boot. Instead it takes me into a system recovery GUI, where I can recover OS partition to factory default. If I select that it lets me sgut down, then takes me right back in when I boot up.

Help!

Thanks, in advance, so much for your assistance.

Chloe

When deleting the Fedora partition(s) you also wiped the Bootloader. You will have to reinstall the bootloader. I guess the Windows Install CD/DVD can do that but I am not sure.

Alternatively you could just install Fedora, and make sure it also installs its bootloader correctly.

Thanks for the suggestion. I've tried using the windows install disc on a USB drive, but reinstalling the bootloader doesn't seem to work. If I try to repair windows via start up repair it says a partition is missing. Starting to think I deleted something I shouldn't have. Any suggestions?

Thanks so much.

Sounds like you have firmware running in (U)EFI mode (not the traditional/legacy BIOS mode) and you deleted the partition where the .EFI files are located that load the actual bootloader. In GNU Linux that is usually a 200MB FAT partition mounted to /boot/efi. If that is the case you would first have to create that partition again (I would do that with a Fedora live system, or Fedora install, or Gparted Live CD/USB), and then re-install Windows bootloader the way you already tried it.

I think it was 2 x 100mb partitions, but you're spot on. Any good guides for how to mount those to /boot/efi? I think I'll use Gparted USB. Never done this before and I don't want to make it worse.

Thank you.

Not sure if I am the right one to help you here since I don't use MS WIN (except for a Virtual Machine) for a long time. I quickly googled, and found this guide here that looks promising to me: The guy boots some Win (8) system and manually re-creates the missing partition(s). Not sure if this is the best way. There should be plenty of guides out there. What you did happens a lot when people want to get rid of their Linux...

Try Create bootable usb windows 10. When boot click on repair computer. Next trouble and advanced option after comandpromt.

Use this:

bootsect /nt60 drive_letter: /mbr

Try using a custom bootloader that lets you boot from a partition no matter if it is bootable. I reccomend WinToFlash Windows XP bootloader that lets you do that.
