What was on /dev/sda?

Oct 5 12:15:18 ubuntu grub-installer: info: Running chroot /target grub-install --no-floppy --force "/dev/sda"
Oct 5 12:15:20 ubuntu grub-installer: /usr/sbin/grub-setup: error: hd0 appears to contain a iso9660 filesystem which isn't known to reserve space for DOS-style boot. Installing GRUB there could result in FILESYSTEM DESTRUCTION if valuable data is overwritten by grub-setup (--skip-fs-probe disables this check, use at your own risk).

On first partition was installed a Licensed Windows 7 Professional 64-bit(100 GB partition) and the other 2 partitions were empty. It was a newly bought "Laptop Notebook HP ProBook 4530s i5 2430M 640GB 4GB ATI HD6490".
I took the next empty partition and deleted it and made it an Extended one. In the extended - first partition made /boot - 250 MB(ext3, tried ext2 too and didn't worked either), then / - 30 GB(ext4), and then /swap - 800 MB.

Did I answered to the question?

I close the bug because Ubuntu 11.10 Release version was able to install on the laptop I was trying to install in Beta 2.
