bootlist OS gone after installing Win XP Pro SP3

[neehs]

Masters,

Good day. My notebook working fine with dual boot with Ubuntu 10.04 & Win7 Ultimate then I install WinXP Pro SP3 on with dedicated 80GB NTFS partition.

I boot it to CD to install XP Pro SP3, then i select the proper / right partition 80GB then it install successfully. The problem is the bootlist OS is gone, I can't select anymore the OS I want to boot on. It direct to WinXP Pro SP3. As I see on My Computer all partition are intact.

Kindly help guys.

TIA

10.04 has Grub2, so please follow the right howto.

Don't tell me you formatted ALL partitions...

Anyway, try this. Format it just this one time, then try doing a partition in the Windows Setup. Make a partition for Windows and another for Linux. Then install Windows. Finally, install Ubuntu on the other partition.

IF you already have a dedicated partition for Ubuntu, and you installed Windows on a partition, most likely your MBR has been overwritten. Try using the liveCD and install GRUB2 on your MBR to recover your first Ubuntu installation.
