Creating a Dual-Boot Windows XP and Ubuntu Laptop

Thank for the great article, I followed your directions and re-partitioned my laptop's hard drive so I could install Ubuntu. The laptop is an IBM Thinkpad T41.

The partitioning step went just fine, so I proceeded to install Ubuntu. (version 6.x, Dapper Drake??) The installation went fine, and I rolled the dice and had it update my MBR rather than do it manually the way you described. This *appeared* to work fine, and I rebooted. Upon rebooting, I have the option to boot into Unbuntu, Ubuntu recover mode, Ubuntu memory test, and Windows XP. I tested going into XP first, to verify that everything on my Windows partition was working and it was. (whew)

However, when booting into either Ubuntu or Ubuntu recovery mode, the entire laptop hard-locks right away after it says, "Uncompressing Linux... Ok, booting the kernel". I have no idea why it's locking-up, but my first instinct is to wipe those partitions and try again. However, what I'm not sure is what to do with the MBR. How can I revert it back to the way it was? I assume if I format those new partitions that Grub will still load and ask me if I want to boot Unbuntu or Windows??

Thanks for any assistance.

    A search on Google for "ubuntu 6 ibm thinkpad t41" brings up a scattering of quotes suggesting people have encountered some difficulties working with Ubuntu 6.x on IBM Thinkpads.

    There isn't an easy way to revert back to your pre-Ubuntu 6.x installation, since GRUB is now your system's bootloader. Since Windows works, I don't recommend attempting to remove the GRUB installation.

    If you format the new partitions you created for Ubuntu, GRUB will still ask you if you want to boot Ubuntu or Windows. In that case, you'll just always select Windows.

    My advice is to get a copy of Ubuntu "Breezy Badger" (Version 5.10) and try installing that into the partition where you currently have Ubuntu 6.x. The installation should see your GRUB installation and it should add options to boot Ubuntu 5 to your current operating systems list. The install probably won't remove the Ubuntu 6.x systems from your boot list, but this can be done manually by editing (carefully) the GRUB menu.lst file.
