ubuntu 11.04 want to skip grub2 entry in installer

Earlier Ubuntu installers would give the option of not installing a bootloader. Now the 11.04 gives a choice of where to install but no option if I just dont want to install bootloader.
Please correct me if I missed something obvious in the Live CD.

I already have a legacy GRUB setup in my hard disk MBR and do not want to overwrite that with a cmore complicated GRUB 2 because there are lot of other entries to partitions like Knoppix, Windows, etc.

I tried:
rootnoverify (hd0,6)
chainloader +1
because Ubuntu installed the bootloader to that partition. It wont boot using this chaining(I hope that's right).

So I have to reinstall 11.04, but I cant find how to skip the bootloader.

The only option I have is to install to disk MBR and risk losing everything in current GRUB and then fighting around trying to restore those entries via grub.cfg of Ubuntu's Grub2.

Any ideas?

Well, grub2 should not have any problem picking up all of your installed operating systems, but you also should be able to chainload grub2 with grub if you did indeed install grub2 to your partition boot record.

Are you sure that sda7 is your / for your 11.04?

If you are unsure then go to

I boot Ubuntu 10.10 with the following entry in Grub Legacy:

title Ubuntu-10.10
root (hd0,6)
kernel /boot/grub/core.img

I can boot with or without the last two lines but know of some systems which need the lines and others which won't boot with them?. Try it both ways.
This would boot sda7 as it is Grub Legacy numbering. If you installed Ubuntu Grub to the / partition of sda7, the core.img file should be there. If the entry doesn't work, verify that file is there. If it is not there, you should be able to copy it from the Ubuntu install CD.

kernel /boot/grub/core.img
worked at first go (even "boot" is not needed), and I did find the Grub2 menu properly installed on the 11.04 partition.
Many thanks for quick replies!
