Help with 'grub-install /dev/sda' Error During Linux Mint Installation
Asked by
CuriousCoder92
I'm trying to install Linux Mint Cinnamon on my computer, but I keep running into an error when executing 'grub-install /dev/sda'. I'm using the "Something else" option in the installer and creating the following partitions:
- 25GB for root
- 8GB for swap
- 500MB for EFI
- The rest of the 500GB drive for home
The problem is that my brother also uses this PC for Windows, so I can't just erase everything. If I can't get this to work, I might have to stick with Windows, which I really don't want to do.

Did you remember to put a space between `install` and `'/dev/sda'`? Sometimes issues come from small syntax mistakes.

It sounds like you might have an issue with the device you're trying to install grub to. Make sure there's no syntax error in your command like missing spaces. Also, ensure you're using stable connections, preferably over an Ethernet cable during installation. After the install, don’t forget to remove the boot media!

Make sure you use the command in the right format. It should be something like `mount /dev/xxx /boot/efi`, and then run `os-prober` followed by `grub-install`. This is the correct method for Debian-based systems!

Check what other block devices are present on your system. Sometimes, the system can have multiple drives or partitions that may interfere with the install. You can use commands like `lsblk` to help identify them.
UserName123: What's a block device? I'm not familiar with that term.
TechieTimmy: Block devices are types of device files that provide buffered access to hardware devices. In simpler terms, these are things like hard drives and SSDs.

LinuxLover88: What do you mean by syntax error? I usually just copy and paste the command.
TechWizard42: Yeah, just double-check to see if you're putting spaces correctly, especially between 'install' and '/dev/sda'.
