Having installed Ubuntu 10.04.1 by wubi from XP I cant boot to start Ubuntu. The install app let me 2 options in windows loader. 1.- Windows Xp Professional. and 2.- Ubuntu. If I acces the frist option I get access to Windows Xp correctly but if select 2. ubuntu it show me the grub screen with the option to boot Windows XP but it tries to upload ubuntu instead, with this error !Unkown command drivemap!".
I am using ECYBCD to recreate boot menu from windows using the bootloader from Vista I can recreate the boot menu. Again with XP no problem, but when I try to boot Ubuntu, the grub menu is broken and what I got is the grub command line grub>.
I try also to boot form here manually with some commands but either send me an error or no such file or no such disk when I try to load the kernel.
Any Ideas
Thanks .

I have had the same experience as described by deco5003.
Only difference /// When I am in the grub screen with only Windows XP option available, when I select that option I go back to the Windows loader.

Thanks
