I had installed Ubuntu 10.04 on an external HDD (Seagate FreeAgent) which was updated to the recent version.
I recently added a graphic card (Zotac GT240). The primary OS is Windows 7. The external HDD has important data which need not to be lost by formatting. Can I reinstall Ubuntu on the same previous version? Can I partition the external HDD?
The previous Ubuntu is currupt. It says no prefix ....and starts booting with the classic purple screen for some time and then gives some scratchy lines as we get if the monitor is loosely connected. Few lines come up saying "noveau00000....failed" and the screen goes blank. for sometime. I have to reset to restart in other OS.
A new issue with the fresh installation of Ubuntu 11.10-------
I created a USB drive with Ubuntu 11.10 iso as per the given instructions.
Booted the comp with the same drive and ran Ubuntu from it.
There was proper initiation with the Ubuntu with the dots below it indicating the progress.
Hopping that the previous problem has solved I was happy. But all in drain with the screen looking patchy appearance as mentioned before with no progress any further. This time the external HDD with previous version was disconnected and the internal HDD with Win 7 32 bit was still connected.
Is there any issue about graphic or MB destabilization?
Today I removed the graphic card (Zotac GT240) and ran the system with on board graphic card (ATI redeon 3200). There was no issue of booting from either the pen drive or the external HDD with Ubuntu 11.10.
However the crazy screen appeared for few seconds and vanished with Ubuntu screen.
I replaced and reconnected the display with the External graphics and the weired screen reappeared.
The issue is with the display of the new graphic card for sure. Now the question is how to get inside Ubuntu to install the drivers.
The driver installation might be taking long time but how long? 15 min with Quad core CPU and 4 gb RAM.
You are absolutely right about the graphic card drivers. I am sure of it now.
When we run a trial boot from a pendrive without complete installation...it should take minimum graphical display to show the classical Ubuntu screen. But even that failed.
I also went through a forum about weired screen in Ubuntu forums. The display image given by one user is similar to what I got.
Hi all. I have the same problem, but i'm found the temporary solution:
1. Insert LiveCD with Ubuntu 10.10(or Kubuntu)
2. After loading menu of CD press F6 and set "nomodeset" option
3. Click "Install ubuntu"
4. Loading and installing must be successfull
5. After post-install rebooting system in GRUB menu select first string and press "e"
6. After words "quiet splash" write "nomodeset". Result must be "quiet splash nomodeset" (without quotes)
7. Click Ctrl+X
8. The system must loading successfull
9. Install new videodriver(Ubuntu must offer this or install from Nvidia website) and reboot the system
Disadvantage: splash screen with "Ubuntu" and "points" now a low quality
Tested on Ubuntu 10.1032 bit , Kubuntu 10.10 32 bit. Hardware: Nvidia GT240 1024Mb DDR5 PCI Express 2.0
