Ubuntu

Can't boot up in new full install OS on my usb

Asked by June Cornish

I downloaded and installed Ubuntu on my usb port without a hitch and it boots up just fine. However, when I do a full installation to another USB, it installs perfectly, but can't boot up in either ext3 or ext4 through my Win 10 system - and I can't install it in Fat32, either or anything else. :( I'm totally disappointed. I can only run it in the 'Try Me' version from my initial usb install (which, ironically, is in Fat32 format).

FAT32 doesn't hold Linux filesystem permissions so is inappropriate to install to. The FAT32 storage you are installing from has basic files then a huge squashfs file containing the Ubuntu OS.

What steps did you take to install Ubuntu to the other USB storage?

You can install Ubuntu to USB.

I understand that FAT32 doesn't hold Linus filesystem permissions (though it *is* the one that works with the original install in the trial mode). That being said, I installed from a usb that had the initial trial system installed and that boots up and runs just fine. However, when I do an installation to another usb from that one and use the ext4 (being told to do that), along with the "/", which does then allow for the full installation to the 2nd usb - it will not boot up from that usb into Linux at all. It appears that Win10 only allows the UEFI OS to boot up *if* it's either in NTSF or FAT32.

Yes it will work because of the squashfs file, as I explained.

Did you install GRUB to the MBR of the drive?
