“How to” Dual boot Ubuntu and Windows 7 (Ubuntu installed first)

[presence1960]

Hi,
I've read the entire thread but can't seem to find the answer to my problem.

I've followed all the steps and after installing Windows 7, re-installed GRUB, etc. But each time I restart, it simply proceeds to Ubuntu.

This is my f-disk l:

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1       26736   214756888+  83  Linux
/dev/sda2   *       26737       29286    20482875    7  HPFS/NTFS
/dev/sda3           29287       30401     8956237+   5  Extended

Thanks, works like a charm.

EasyBCD is crap in my opinion. GRUB works better and is way more customisable. But to each his/her own.

With Win 7 & Ubuntu 9.10 (grub2) is the same solution as with grub (1) ?

No, grub two is entirely different. When I get time I will add a section for grub two, but for now try searching in google.

I installed ubuntu 9.10 first and then installed Windows 7. After that i followed the tutorial here to reinstall grub. After i ran the command update-grub, it detected Windows 7 automatically and added it to the grub.cfg file. However, now when I try to start windows from the grub, It doesn't load windows and instead just shows the grub again after a second. Here is my fdisk -l

Disk /dev/sda: 120.0 GB, 120034123776 bytes

Is that the correct partition you have windows 7 on ?
