openSUSE 12.1 GNOME x86_64 installation and dual boot windows 7

[piyushlpn]

I am trying to install openSUSE 12.1 64bit in my laptop(Dell intel core i5,4gb ram,64bit,ATI 550v 1GB) alongside windows 7.I want to install it in the 40Gb unallocated space that i have created in windows as shown.But while installing ,openSUSE suggested some kind of partitioning which i could not understand.please check the screenshots and suggest me what to do.

Well the solution is :

1. You will need to remove all the partitions from your hard disk. Since Dell has pre-installed the OS on your hard disk with its own recovery partition it makes the mbr unchangable, which is what any linux will try to do.

2. Backup everything on your hard disk.

3. Remove all the partition and create fresh partitions from within windows and and install windows 7 from DVD [ not recovery DVD ]

4. Now install Linux in the 2nd partition you just created.

I think OP needs some free unallocated space to install Open Suse and there's should be three partitions like :

/boot - set it t at-least 200 MiB
/root - all your data / program files will be here so make it as large as possible
/swap - the linux pagefile

Howmuch space is required(i have given 40GB)?
And i could not set /boot /root /swap because while doing custom partition i am getting error shown in screenshot-4

Manually partition the hard drive yourself and allocate the unallocated space as topgear suggested. Create partitions like
/boot - 200MB
/root
/home
/swap - 1GB

NOTE: Backup before you do anything.
