Grub2 install failed with “unable to identify a filesystem in hotdisk… safety check can't be performed”












0















On a VM-ware insatnce, I am trying to install grub2 bootloader onto a brand new SCSI disk. I want to install it onto the disk's MBR.



I run sudo grub-install /dev/sda and got the error "unable to identify a filesystem in hotdisk//dev/sda; safety check can't be performed."



Questions




  1. What am I doing wrong?

  2. And why is there a need for a filesystem? I thought since I am trying to install it to the MBR (not a partition's boot record), it should not care about filesystem/partition. I should just simply write the bootloader to the first 512 bytes of the disk.

          4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
