Trouble concerning Mageia installed on external USB disk

[frananc]

Hello everyone!
Wanting to test this operating system I've read positive reviews, I installed Mageia 4 into a partition of external USB hard disk drive to my Dell Inspiron 6400, which has as its main operating system Linux Mint 17.
The grub of the latter correctly identified Mageia and allows it to start.
I get the screen usual image, with blue sky background and the text.
After waiting for about a minute, however, the image disappears and the entire screen displays:< Welcome to emergency mode! After logging in type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, "systemctl default" to try again to boot into default mode. Give root password for maintenance (or press Control-D to continue)>.
I tried to follow the instructions but to no avail.
By accessing through failsafe I got the image attached.
Some advice? Any help will be appreciated!

Check https://wiki.mageia.org/en/Mageia_4_Err ... rrect_UUID
Either uncomment the offending entry in /etc/fstab, or in Windows 8 disable the hybrid shutdown, which leaves the disk in this state.

Hello Doctor, first of all let me thank you for your help. I created into the folder /etc/grub.d in the main operating system a file I called 42_custom, as below
cat << _EOF
menuentry 'Mageia 4 on sdb9' {
Set Root = (hd1,9)
multiboot /boot/grub2/i386-pc/core.img
}
As a result I get mageia booting regularly (and fast!), showing the normal screen and soon after what you can see in the attached image.
Where am I wrong?

Hi.
I seem to be unlucky (or not very capable ... ).
I deleted the file created earlier, and then edited grub.cfg as suggested, but I get the same result!
Some additional tip?

Your last screen shot complains about a missing partition.
Did you delete or format a partition using Mint or was it on another removable drive not plugged in now?

Hi Ken. Thanks for your reply. I installed Mageia (one partition for root, one for /home, one for swap) in an external usb disk, alongside other OSs under similar conditions. The main OS (owner of the grub) is Linux Mint 17, that stand alone in a PC.

Hi Ken. Thanks for your reply. I installed Mageia (one partition for root, one for /home, one for swap) in an external usb disk, alongside other OSs under similar conditions.

If you had another USB drive plugged in with a swap partition on it when you installed Mageia the installer would have seen and used that swap partition along with the one on your internal drive and the one on your Mageia drive.
If any one of those swap partitions is missing you'll see the error in your screen shot.
