Hi,

I installed dsl (complete install, not frugal) to hdb2. During installation I choosed Grub as bootloader. The question "Do you have windows on hda1?" appeared and I answered "yes".
Then I had to reboot. But the machine booted windows, there was no dialog where I could choose the os to be booted. What may have gone wrong? Is grub installed on hdb2? How can I check this and how can I move it to hda1?

I hope somebody can help me.

Thanks in advance

Michael

I had to move my Windows drive to the slave position, then install grub and DSL on the (now) hda drive. I'm sure there are other, more elegant, solutions. I suspect that you have grub on the MBR on hdb.

i installed dsl on hdb1, the only partition on my only hard drive, and when i restart, it says "grub hard disk error". i tried both full install and frugal install, but the same error both times. any ideas whats wrong?

(i have hdb set to slave in the 2nd ide spot, i have another hadrdrive that i switch to by manyally connecting it and disconecting hdb2 when i need it.)

That's how I solved the problem

1. Start ATerminal
2. sudo su
3. grub
4. find /boot/grub/stage1
the answer was (hd1,1)
5. root (hd1,1)
6. setup (hd0)
7. reboot
grub showed 5 versions to start dsl but not windows
8. login and load /boot/grub/menu.lst into an editor
the last lines in that file are:

#title Windows
#root (hd0,0)
#chainloader +1
#makeactive
#boot

9. removed the # from each line mentioned above and saved the file

10. reboot
grub now shows "Windows" in the menu

I hope that helps

Hi.

My guestion is simple, How i can enable dma before grub tries to mount root at start?
I need it because i have SiS hd controller and dsl cant find/mount my partitions/hd without dma acceleration, and i have normal hd install and it gives Kernel panic when trying to start without dma. Error message:
Kernel panic VFS: Cant mount root on 03:01. or something like that.

Is it even possible to do it?

Frugal install works fine.
