Can't boot from external SSD
Can't boot from external SSD
Hi,
yesterday I decided to use Debian Sid as my default OS for gaming (to have all new drivers and other stuff like this) so I downloaded the stable installer (CD) but there were missing some drivers for my WiFi Network though I had LAN inserted. Then I tried the testing installer (CD) and the weekly & the normal non-free (CD) installer with the same result. Only the non-free (DVD) installer worked (the only one that has detected LAN) and I installed Debian stable to my external SSD (GRUB too). Now I wanted to boot from this SSD but it only shows a black screen with an flashing underscore at the upper left hand corner.
Best,
NewHere
Edit: BIOS detected SSD after using it inside another OS.

Re: Can't boot from external SSD
Does grub load at all? Or, is it that when you choose your external SSD from grub, it takes you to the black screen with flashing cursor?
Also, to be clear, are you using Sid yet, or still on stable (Stretch)?

Re: Can't boot from external SSD
I tried to start GRUB but ut doesn't load or doesn't show.
No, this would be the first boot (i.e. not changed the config to use unstable repository yet).

Re: Can't boot from external SSD
If you're able to load in a live environment (I'm assuming that's what you meant by "another OS", but please clarify if you meant something else), try chrooting into your SSD install, and take care of grub from within the chroot.NewHere wrote:I tried to start GRUB but ut doesn't load or doesn't show..
You might need to install grub to your device first. On my system, for example, I would run the command: grub-install /dev/sda; if you have a separate boot partition, you'll probably want to install it there, instead of the whole device. Being an external ssd, you may want to do some research on the best place to install grub. I want to say it would be an internal location (ie, your internal hard drive/ssd), but I've never done that, so don't quote me on it.
Then, run update-grub, and check to see if grub actually notices your Debian install.

Re: Can't boot from external SSD
Can we please see the output of these commands (with the SSD connected):
https://packages.debian.org/stretch/parted
https://packages.debian.org/stretch/efibootmgr
Those commands can be run from the "live" environment.
Code: Select all
# parted --list
# efibootmgr -v
https://packages.debian.org/stretch/efibootmgr
Those commands can be run from the "live" environment.

Re: Can't boot from external SSD
To boot your system from a USB key / disk I used this:
http://cosmolinux.no-ip.org/raconetlinu ... tence.html
Works great, I've enabled webdav under 443 so that it does the same as by normal boot disk (internal).
In case of emrgency I can boot from usb and ahve the whole server back inot the air in a few minutes with the same features...
Some changes are needed on webdav config files, but if you know how to install that normally.. you will finds your way.\
PS: Change the iso names to the right one to be able to install it....

You could do a search and find the answer to that:
keywords:
I did it for you this time, and there are some links that go into details:
https://wiki.archlinux.org/index.php/GNU_Parted
https://packages.debian.org/stable/parted
https://packages.debian.org/stable/gparted
Then there is "gparted"
https://gparted.org/display-doc.php%3Fn ... elp-manual
You can also use the 'fdisk' command,( the simplest and easiest method)
for details :

Re: Can't boot from external SSD
Thanks for the research, I did a research on my own but wanted to be sure this time
I'll try it out.

Re: Can't boot from external SSD
It wasn't set but after choosing the right partition for booting it's still not working.
