I installed (nearli successfully) ubuntu in one of my laptop partition.
I also have windowsxp and I'm using Grub as bootloader.
But there is still a problem.
When I logout from Ubuntu and restart the computer to pass at windows, windows boots up but I can't login! And I can't neither turn off the machine. Then I swith off the power and start again windows. It obviously checks the disk and just then I can login.
This happens every time I pass from linux to windows.
What can I do?
So grub doesn't apear each time you booy up after the instalation?
No Grub appears every time.
If I select Ubuntu no problem.
Instead if I select windows, the screen of windows appears and then the icons with login usernames appear. But If I click on the icon with my username all is freeze. If I click on "turn of" also it is also freeze.
So I turn off the power and after the reboot and windows selection in grub and the automatic "scan disk" I can click on my username and normally go in windows.
Ok, so no matter what, if you turn off the power instead of rebooting, you can load Windows fine? Try passing acpi=off in your /boot/grub/menu.lst and see how your reboot to Windows goes.
Are you mounting your C: partition in Ubuntu?
but in wich point of menu.lst must I write acp=off?
About your 2 question:
I mounted Windows uder ubuntu too see my windows files from linux.
I also noticed that if I select "shut down"
from ubuntu, the machine restarts! Not good.
First, it's acpi=off, and it's in the kernel line of the Ubuntu section. It looks something like this:
# (1) Ubuntu Linux
title Ubuntu Linux
kernel /boot/vmlinuz-184.108.40.206-2-686 root=/dev/hdd1 acpi=off ro quiet splash
I'll try and let you know.
I added acpi=off where you told me. but nothing changes at windows boot and again if I select "shut down" from ubuntu it reboots.
