Grub error: Can’t find command ‘grub_platform’

[x1ricardo]

Can’t find command ‘grub_platform’ while trying to boot using a pendrive.
I can not find a solution for this.

After an eternity with the black screen it finally booted from the usb. It seemed like a error, that's why I put the post. Apparently it was a matter of waiting a long time.

yep---especially older usb2 devices--cobwebs wait

is the system installed on the usb? (pendrive)

Did you find a solution? There is one over on AskUbuntu.

I tried it and it works but it is painfully slow. Like 1/10 the normal speed. Be prepared for long, long waits.

If the USB drive is /dev/sdc:

Code: Select all

sudo gdisk /dev/sdc
    Enter r for transformation.
    Enter g for converting GPT to MBR.
    Enter w for writing to MBR partition.
    Enter y to finalize and exit.
    
sudo fdisk -l /dev/sdc
