[SOLVED] Windows missing from grub after install

Greetings everyone!

Installed Arch a few weeks ago and havnt looked back, havnt even WANTED to boot into windows. However, now I want to. I want to go back into windows to resize my windows partition to teeny-tiny and make my arch partition reeally big and there is a too that I like to use for that that I am really comfortable with called Easus Partition Manager. I've tried doing this myself but haven't had any luck. Here are the results of fdisk -l and my /boot/grub/menu.lst

Disk /dev/sda: 1000.2 GB, 1000204886016 bytes

Re: [SOLVED] Windows missing from grub after install

your windows root is incorrect. grub is 0 based.

so your entry should be (hd0,0) for disk 1 partition 1 assuming that sda1 has the windows boot files

Re: [SOLVED] Windows missing from grub after install

Also, I am quite sure you cannot boot Windows if chainloader +1 is commented.

Also, I would like to recommend gparted for partitioning. It's really simple and intuitive to use.

Re: [SOLVED] Windows missing from grub after install

wahoo, thanks mates, that got me in just fine, for reference.

in device name conversions changed

/dev/sda        (hd0)  to
/dev/sda1      (hd0,0)

rootnoverify (hd0,3)  to
rootnoverify (hd0,0)

#chainloader +1  to
chainloader +1

however x33a, i believe i'm going to take your advice and give gparted a try, i hear so much nice things about it and would love to know more!
