View Full Version : [ubuntu] Black screen and flashing cursor after install

After installing Ubuntu Server 10.04 LTS, I restarted my machine. I removed the disk, but now when it starts, it never gets to GRUB. Instead, it just takes me to a black screen with a blinking cursor. I can't type in anything and holding shift doesn't take me to GRUB.

Any advice?

I would recommend to try once again press and hold down Shift key from your Bios screen. You can try with both the Shift keys one by one and see if it takes you to Grub menu.

Or if not, I wonder if Grub was correctly installed. For diagnosing that, we need to you to boot an Ubuntu Live CD/USB (desktop edition) in Try mode and post the output of bootinfoscript as per instructions here.

While posting, click the # icon in post menu and paste your text in between the generated [code] tags.

Thanks for the quick reply. Here is the contents of RESULTS.txt:

I'm wondering if I didn't install something right? Under sda1 everything is blank :confused:

So you've got three hard disks and Ubuntu is on sdc whereas Grub is installed in the MBR of sda. You need to get it in the MBR of your sdc. But before you do that, make sure you've got an option in your Bios menu to make your sdc, the first boot device.

There are numerous mount errors in the output you posted above. If you plan to format both sda and sdb HDDs, that is not a problem.

So from the booted Live CD, follow the commands below.


sudo mount /dev/sdc1 /mnt


sudo grub-install --root-directory=/mnt /dev/sdc

Note, for the 2nd command it is just sdc without an integer and not sdc1. Reboot and make sdc first boot device. Lets hope it boots Ubuntu successfully this time.

I have a similar problem, but my screen does not stay blank, is goes to de "Grub rescue>" but saying "Unknown filesystem"

My Boot info from the live CD says:

My guess is that because it is loading from a SATA drive in the 4th position and this new computer (custom build) is more likerly to work with a HDD in the 1st or 3rd SSATA pusition, I most change something, but the CMOS/BIOS is set to start from sda... not sure what to do.

My problem is similar to scarypajamas except I am still stuck. I installed 10.10 x64 onto a virgin system. I started with the "try" option and selected "install" while there. The install seemed to go fine.

When I reboot there is a short series of cursor flashes and the screen goes black. A few seconds later, the drum sound from the login is heard. I hit enter and entered my password and the login song played. ---STILL BLACK SCREEN.

When I tried to boot again from the CD, it, too goes to black screen!

I finally got Puppy Linux to load (that's where I am now) and tried the bootscript thing.

The RESULTS.txt file is attached.

All help is appreciated.

After looking at the cchtml.com Ubuntu Maverick Installation Guide, I was able to shutdown my system correctly and reset xorg.conf through a series of Alt-PrtScr-? entries.

I then had a usable GUI. I loaded the restricted Radeon drivers, reset my screen res and was ready to go.

Mine is still not solved. I am attempting to install the Grub on sda1 instead of sda6. No video card issues here, Linux and Windows cannot read the HDD once I installed either.](*,)

So you've got three hard disks and Ubuntu is on sdc whereas Grub is installed in the MBR of sda. You need to get it in the MBR of your sdc. But before you do that, make sure you've got an option in your Bios menu to make your sdc, the first boot device.

Oh, how silly of me! I was able to fix the problem as you said by using a recovery CD and installing grub to sdc. Thanks for your help!

hi ubuntu users,

I have same kind of problem. I have two disks. I have installed 64-bit ubuntu 10.10 and now I am trying to install 32- bit Ubuntu 10.10. I took advice about installing grub. You can find my RESULTS.txt as an attachment. Although it seems grub 2 is installed on both disks, reboot is again unsuccessful. Thanks for your help.

Grub is not installed properly. Boot an Ubuntu Live CD/USB and follow the commands below.

These 2 commands will install Grub in the MBR of your sda drive for the Ubuntu install present in sda2.


sudo mount /dev/sda2 /mnt
sudo grub-install --root-directory=/mnt /dev/sda

Note, for the 2nd command it is just sda without any integer.

And these will install Grub for sdb for the install present in sdb2.


sudo mount /dev/sdb2 /mnt
sudo grub-install --root-directory=/mnt /dev/sdb

Reboot, select either of your HDD as the first boot device in Bios and then from Ubuntu' Terminal, run this command to add the other Ubuntu install to the Grub menu.


sudo update-grub

Good Luck!
