I am trying to configure my laptop so as to be able to dual boot Windows 7 (64Bit) and Arch Linux.The laptop on which I want to do that came pre installed with Windows 7. The installation consisted of 2 partitions: the first one 5360 MB in size, obviously being a recovery partition, the second one, using the rest of the harddisk, with Windows itself.Windows is booted by BIOS through/via MBR.Here's what I have done so far.Went into Windows and shrank the second partition to make room for some linux partitions.used Arch Linux live cd to startup Linux environmentcreated primary partition /dev/sda3 (100MB for /boot)created extended partition /dev/sda4created /dev/sda5 .. /dev/sda10 for /, /home, /var, swap and two spare partitions.installed Arch linux packages (so that, for example, /boot/grub or /boot/vmlinuz-linux is existing)And here's where I am stuck.I figure I should do something with grub (but am not 100% sure about that) so that it loads either Windows on /dev/sda2) or /boot/vmlinuz-linux (on /dev/sda3) but I have no clue how I would proceed, especially that I am not destroying the Windows booting mechanism.
I am stuck with the next step to setup a dual boot for Windows 7 and Arch Linux
arch linux;windows;grub2;dual boot
pacman -S os-probergrub-install /dev/sdX   (do not use partition number)grub-mkconfig -o /boot/grub/grub.cfgAnd then you should be all set to go, as long as os-prober is installed, it will let grub detect and preserve the windows boot partition.Note this is NOT for EFI motherboards.
