Purple Screen / bootinfoscript / e2fsck

[andrewandrew]

Hi there

I am getting a purple screen at bootup.
I have used a bootable usb stick to run bootinfoscript and I get the attached results.

Can anyone help me decode these results and suggest some actions for fixing my system.

You have wubi.

But often purple screen is video issues. But it looks like you may have Intel SRT?

Do you boot Windows, from Windows get Windows or Ubuntu, and then get a grub menu? Do not know if this works on wubi or not.

If you have Intel SRT I am not sure wubi works. The Intel uses some sort of RAID which complicates Linux installs.

Hi there,

Just to give you a bit of back ground. I have a dual boot set up on my machine. Initially I was running windows 7 and I followed a link on the Ubuntu site which setup a dual boot loader and installed Ubuntu.

This has worked fine for about 9 mouths. Recently, when I rebooted I got the purple screen which hangs.

I have been able to boot windows 7 from the boot laoder with no issues.

I have also been able to boot Ubuntu while holding down the shift key which allows me to enter a recovery mode.

Could any one give me a bit more help?

Cheers
Andy

what you call "purple screen" is in fact "plymouth" (which is required by the system) and its "splash screen" (which can be remove/desactivated to get a verbose boot mode). If you remove "splash" from the boot line, then you can see the possible warnings/errors while booting.


sudo gedit /etc/default/grub

here erase "splash" and update grub then


sudo update-grub

that is the "permanent" change, for a single try, simply hit E for editing the selected ubuntu boot line from the grub menu, remove "splash" and hit ctrl+X to continue booting.

Thanks Dino - I will give this a try when I get home tonight.

I am getting the following error message.
Try (hd 0,0):NTFSS: No wubidr
Try (hd 0,1):NTFSS: error:"prefix" is not set.

Any clues?

While booting in recovery mode the process hangs at the point shown in the attached pdf.

I might try fsck on the wubi file from a liveCD or flash drive. Change example to your partition containing root.disk. sda3?

http://ubuntu-with-wubi.blogspot.ca/2011/08/missing-rootdisk.html
sudo mkdir /media/win
sudo mount /dev/sda1 /media/win
sudo fsck /media/win/ubuntu/disks/root.disk
Then check if you can mount it & read it:
sudo mount -o loop /media/win/ubuntu/disks/root.disk /mnt

I cannot thank you enough - that last suggestion fixed my system and I'm up and running again now.

Cheers

Glad that worked. :)

If you find you like Ubuntu, you may want to consider a full partitioned install. Bit of work to reorganize partitions with Windows 7 as it like to use all 4 in MBR partitioning.

From the developer of wubi:
http://howsoftwareisbuilt.com/2009/03/12/interview-with-agostino-russo-wubi-ubuntu/

Agostino: Wubi actually wasn’t designed to do long-term installations. The main aim was really to let people try out Ubuntu with confidence. Normally, users that start with Wubi tend to upgrade to a full installation to a dedicated partition at the next release cycle.

Hi there - it just failed to reboot again. So I repeated your procedure and I'm running again.

I think I need to migrate to a new partition. I have created a new partition using Gparted.
Which option should i format it with?

[bcbc]

When you migrate, the script will reformat the target partition as ext4. As long as you have it as ext2/3/4 it will be accepted.
