Ubuntu 10.10 winxp dual boot error 15

I have a HP Mini 110.

I had dual boot win xp and ubuntu 9.04 working well.

I tested Ubuntu 10.10 desktop live cd. everything including wifi and mobile broadband worked well. (netbook version was confusing and i could get mobile broadband to work)

So I went installing Ubuntu 10.10 desktop over 9.04 keeping win xp in tact.

I chose the option specifying partitions since I could get guess effects of 'simpler' options. :-)

I chose to install bootloader in sda6. Perhaps that was big mistake though I thought about it.....

Installation proceeded smoothly.

When I was asked to reboot, it failed to boot -not even winxp could be booted.

Please help with the simplest method. I am business user.

I read various answers under error 15 and felt that they all dealt with somewhat different situations.

Hemant
