After installing, the GRUB screen shows up

[silver2049]

I installed Peppermint OS on to an external hard drive, using a Live USB but when I  tried to boot it after finishing the installation with no problems, it showed the GRUB prompt and I'm not sure what I can do now to fix it.

What is being displayed by the "GRUB screen" ?

What is on the internal HDD ? .. ie. was this a dual boot setup with Windows on the internal drive and Peppermint on the external drive ?

Can you also boot to the Peppermint LiveUSB and post the output from running these 2 commands in a terminal:

Code: [Select]

sudo fdisk -l

and

Code: [Select]

sudo blkid

This is still an active topic (not marked as solved /closed / abandoned) so please start your own topic.

If I reply to you on this topic and my reply is different from what I'd say to the OP it would become rather confusing.

Sorry for the REALLY Late reply, i thought i would be notified when i got a reply.

Anyways this is what showed up when i ran sudo fdisk -l :

Also, my setup was Windows on my internal, Peppermint on my external

[PCNetSpec]

Are you still able to boot Windows ?

[silver2049]

Yes

[PCNetSpec]

Hmm....

I take it your external HDD is the one with a partition labelled "PASSPORT" .. so I'm guessing it's a WD Passport 1TB ?

If so, then it doesn't contain a Linux partition, just a swap partition and an NTFS partition

Can you install gdisk:

Code: [Select]

sudo apt-get install gdisk

then post the output from:

Code: [Select]

sudo gdisk -l /dev/sda

[silver2049]

Wait sda or sdc?

[PCNetSpec]

sda

I want to see the partition layout on the internal HDD .. but it has a GPT partition table so fdisk can't read it .. gdisk can.

I'm just trying to figure out what happened to the Peppermint installation as it appears to be missing

OK, I'm lost as to where Peppermint went 

I take it you selected "Something Else" at the partitioning section of the installer ?

What is the goal here ? .. to resize the NTFS partition on the passport then install Peppermint to it, installing the bootloader to the external drives MBR (so the external HDD is bootable on other PC's and so the Linux bootloader doesn't overwrite the Windows one, breaking Windows) ?

If so, how much room do you want to allocate to Peppermint on the passport ?

is this a laptop or a desktop ? .. are you able to disconnect the internal HDD whilst installing Peppermint (for safety sake) ?

[silver2049]

Yeah I selected, "Something Else" for the partitoning section.

In the partitioning section, what I did was allocate 100 GB for the swap space (because I thought I could put as much as I wanted), and the rest went to hard drive space, and I only chose installing the bootloader on the HDD because I thought that's what I was supposed to do.

And this is a laptop.

[PCNetSpec]

How are you able to boot Windows ?

I'm assuming either

a) the bootloader didn't get written to the Windows MBR because it's protected
or
b) you chose to install GRUB to the MBR of the external HDD .. and choose which HDD to boot from with the BIOS or boot device selection screen ?

Can you explain exactly what you have to do to get the flashing GRUB prompt ?

And what you have to do to boot Windows ?
