how to dual boot win7 and blenderbuntu

Gabriel Knight

Hi, I dont know how to dual boot win 7 pro and blenderbuntu as a clean
install of both, blenderbuntu OS is for blender 3d I have tried to install
win 7 first and then blenderbuntu but I dont know very much about all things
ubuntu and linux. I have one hard drive in my laptop with two partitions one
for 7 and 100mb or near for the default system files of win7 then I
installed win7 and shrunk to make another partition at 50GB, then I ran
blenderbuntu to install it and made another two partitions (from the first
one made in 7) one for a swap file at 5GB and one for blenderbuntu with ext4
and mounted as " / " with the remaining space now when I boot the laptop it
always boots to win7 and there is no option to choose which one to use. Have
I done something wrong in the mounting should I have used " /boot " instead?
There is an option to install along side with win7 but it does not let me
choose the partition I need so I think it is installing on NTFS I dont want
this. Please help!

Thanks GK.

You should try the associated blenderbuntu forum for advice and how to
do this.

If you install Windows 7 first, and then Ubuntu, then you'd need
something like a "chainloader" entry in Ubuntu GRUB. If Ubuntu is
any good, it should automatically see Windows 7, and put it as
an item in the boot menu.

Otherwise, you'll need to edit the menu file in GRUB.

This is tedious stuff. Keep a waste receptacle handy, for
your hair loss :-( I hate fixing this kinda stuff.

http://askubuntu.com/questions/135272/how-to-boot-into-windows-7-when-grub-is-installed-in-the-windows-partition

"Currently your grub.cfg uses the GRUB boot commands below to boot Windows 7.

menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os {
insmod part_msdos
insmod ntfs
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root 1EA0019AA0017A13
chainloader +1
}

I am suggesting you try changing this and use these commands instead.

menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os {
insmod part_msdos
insmod ntfs
insmod ntldr
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root 1EA0019AA0017A13
ntldr ($root)/bootmgr
}

"

Now, doesn't that look like fun ?

There shouldn't be any problem. He mentioned the install alongside window
7 option. Since that is what he wants that should have been selected and
grub would have replace his mbr. I like to save then mbr before doing
this. You can use mbrwork.exe from www.terabytesunlimited.com. HP have a
utility to make a dos bootable usb stick.
