I have a problem and I couldn't solve it by searching in google. My problem started with a USB modem that worked fine till one day it suddenly did not work anymore. I tried to solve the problem by following some instructions on google.

  • First I changed the mount options... didn't work
  • Then found a post suggesting to install Huawei drivers for Linux, installed and still didn't work.
  • I found and used these installation instructions. Package installed was HUAWEI Data Cards Linux Driver.zip from the same link.

I shut down the PC. The next startup, it didn't boot. I followed instructions to fix GRUB, after fixing GRUB with a live CD, PC restarted and came to screen error with low graphics mode. I clicked ok and the PC just stayed hanging.

After a long time I restarted the PC and then it booted up into GRUB prompt. Followed some instruction to fix this. After loading the kernel and booting, it reaches a point where the screen flasher and show verbose login info, I then have to hit Alt+F2 to get back to login screen.

Every few seconds the screen flashes again and show the verbose info very briefly then the screen goes blank. How do I fix this?

Let's see if we can undo the driver installation with it's Uninstall program:

  1. Boot a live system and set up a chroot environment for you local Ubuntu installation (see steps 1–6 of this answer).

  2. Navigate to the directory where you extracted the Huawei modem driver and run the uninstaller:

    cd /path/to/huawei/driver
./Uninstall

  3. (optional) If you think your Grub installation or configuration may be broken you can continue with the remaining steps 7–9.

  4. Exit the chroot environment and reboot (as in step 10).

One part of this problem was solved with the information in comments. I installed Ubuntu again on the same drive, re-partitioning the drive during installation and leaving the old installation on the first partition. When the installation was completed, I could access my first partition through the new installation. Now I can move my files over to the new installation without a hassle.
