>>> Problem Solved with the help of toracat giving me the virtual swap documentation's link
(Original post edited) ----- Hello everyone I successfully installed SL 6.2 but I have a Grub configuration problem : windows do not boot with my grub entry. Before the installation process, I've unplugged my data HDD and my Windows HDD so I do not mess with important files. That's why Anaconda did not set this automatically.
When I plugged back thoses disk, I also wanted to have a windows entry in grub so I do not have to do bios setup to log into windows (that's why a bootloader is made for, right ?) I can not find any automatic graphical tool to set the grub config for me (like it does in anaconda in the SL 6.2 installation process) The menu I've first edited was showing up at boot, but windows did not not boot (but it was if I booted the disk from bios settings) So I have written windows entry in the /boot/grub/grub.conf file, here is my file content (edited : working):
I was looking for an equivalent to "update-grub" (debian style) OR "grub-mkconfig -o /boot/grub/grub.cfg" in Scientific Linux 6.2... because I did not succeeded to use the standard "Grubby" package... ==> I did not found any "updade-grub" function... and it's normal, because it's a grub 1.x. and the only thing to do was to édit the grub.cong with the right parameters. ==> if you need to adapt your grub conf, and do a virtual swap, just swap the disk grub is in with the one windows is in. The disk order depend on how you configured it on you bios (or the slot order you plugged them if you did not changed anaything in bios. -------------------- Give a man a fish...

The problem is most likely because Windows is not on the first drive. There are workarounds for this. For example, see this article for more details.

Thanks for the tip.
Am I supposed to enter something like that :
But how can I make grub to take my grub.conf into account ? What is the equivalent to an update-grub (debian clones) in REHL clones ? -------------------- Give a man a fish...

Normally you do not have to do anything after editing the grub.conf file. If you need to [re]install grub, there is a command called 'grub-install'. Your 'rootnoverify (hd0,0)' does not seem right. If Windows is in hd2, it may be more like (hd2,0). Try looking at the output of 'fdisk -l' and determine the exact numbers to enter. -------------------- ELRepo: repository specialized in hardware support for EL

Oli, Did you get this working?
I have the same problem ( I installed linux in a primary hard-drive, and windows on the secondary). I edited grub.conf just like you had written, but I am not getting the boot menu after a restart. I go straight into SL6.2! Thanks for any help! |

Edit the grub.conf file and delete (or comment out) the line that says hiddenmenu and try booting again. -------------------- ELRepo: repository specialized in hardware support for EL

Thanks to both of you!
I had a bigger problem. I had installed Win XP on my primary disc, Win 7 on my secondary disk, and then did a format and install of SL over win XP. This lead to a NTLDR missing error when trying to bootup win7. I simply moved the Win 7 to the primary slot, disconnected the drive with SL, put in my Win7 installation disc, and then re installed the bootrec using this http://support.microsoft.com/kb/927392 ( I used the /FixMbr option for Bootrec.exe). I also edited the grub file accordingly, and now dual boot works! Thanks again Toracat and Oli! |
