Cannot boot to anything after installing Ubuntu dual boot

Hello. I just tried to dual boot Ubuntu alongside Windows 10. I created the partitions for Ubuntu correctly, including swap and EFI partition and the install went through successfully.

 

Upon reboot, I expected to be put into the GRUB menu but instead I was put into the BIOS which means it cant find the bootloader.

 

I cant access Ubuntu or Windows now. I only have an Ubuntu live usb. What do I do??

You could try to repair the Grub installation: https://howtoubuntu.org/how-to-repair-restore-reinstall-grub-2-with-a-ubuntu-live-cd

 

Did you have any other drives attached during installation? It's possible you installed the boot loader onto another drive/USB stick by accident.

The ubuntu install had a location of where to install the GRUB boot loader and my NVME ssd (where windows is also installed) was selected

Just on the off chance... did you switch the BIOS back to booting from the NVMe, after using the USB stick to boot/install Ubuntu?

I never changed the boot order. I just override the boot to the USB stick in the BIOS for that one time. If it boots to my NVMe drive, it doesnt find anything.

Would it be possible to just delete everything related to ubuntu and still boot to Windows because all the files are still there.

That wouldn't restore Windows' boot loader. I would try the repair I linked to from above.

Where do I install grub? On the fat32 partition that I created in the ubuntu installer?

When it asks for a device for boot loader installation, you normally select the disk, not a particular partition (e.g. "/dev/sda" not "/dev/sda1"). It is normally written to an area just after the disk's master boot record (MBR).

 

Any reason why you went with a FAT32 partition for Ubuntu instead of EXT4 or any other Linux partition type? I think this might actually be causing issues.

 

Since this is a fresh install, I think it might actually be easier to simply reinstall Ubuntu. I would remove the partitions you created during your installation attempt and tell Ubuntu to use the free space and then let it create partitions automatically (there should be an option like "Use available free space" or "Install alongside Windows").

I'm forgetting about Ubuntu now. I need to fix my Windows install. I've removed all the partitions relating to Ubuntu and I've just tried to fix the Windows boot files using repair my computer through the windows setup USB.

 

I tried bootrec /fixmbr and bootrec /fixboot but these didnt work.

 

Am I completely fucked here? Do I need to format my SSD and start again? Thanks.
