Windows 7 Ultimate x32 With Sp1 + Vista Ultimate x32 with Sp1 & Sp2 !!

Hi Isoya,
Glad to know that your problem is resolved! I just answered your questions / suggestions & the result is positive.
All thanks to SIW 2. It was not possible without his WinRE iso.

1. I have purposefully made that 200 MB unused because i have some plan for that. I would suggest using it the way it should be used ideally.

I would also brief the cause of the original problem & its solution.

Please wait for the next instructions today evening or tomorrow.

Thanks & Regards. ...

Windows 7 Ultimate x32 With Sp1 + Vista Ultimate x32 with Sp1 & Sp2 !!

Hi Isoya,

1) Keep this free 3rd party Portable Partition Manager on your PC.

MiniTool Portable Partition Magic Brings Easier Disk/Partition Management

It's very powerful, accurate, fast & easy!
For eg.
It lists all the partitions on the disk. Also the hidden once which are not shown/mentioned in default Disk Management.
It gives options which are not available with the default one.
And it's easy to use.

2. A few things to check, Need not fear anything or do anything, Just watch & report :
Shut down your pc, connect both the disks : Ubuntu & win 7 & start it.
you don't have to choose anything, you have to just start the power on pc & just tell what are the things that happens automatically during the process :
(i) What are the choices provided ? Are you offered Ubuntu & win 7 boot options ? I think you will not see a nice looking multiboot choice screen.
(ii) Which is the OS you finally land into by default ?
(iii) With both the disks attached, can you boot in both of them one by one ?
(iv) What options are provided when you choose to boot into win 7 disk & When you choose to boot into Ubuntu disk ? Anytime any problems, any ODDS and / or issues /errors ? Anytime you get a multiboot choice screen ?

3. Keep both the disks connected, boot into win 7, launch 'Minitool Partiton' program, take a screen shot & share it with me.
Take care that the partition wizard window is enlarged , it shows both the disks & the quality of the screen shot is good enough.
Disk Management - Post a Screen Capture Image
I am giving this link only for points 5th & 6th. So that you can manage a good screen shot with the win 7 in-built Snipping Tool. You have to use Minitool Partition Wizard & not the inbuilt win 7 Disk Management.

Let me know.

Thanks & Regards. ...

Windows 7 64-bit

It boots whatever HD I set first in the boot order, One HD is connected to the main internal SATA connection and the other is using a SATA to USB line and is plugged into USB.

Booth GRUB (for ubuntu) and the windows bootmanager does not recognize (or isn't set with) the other drives. (i.e. when setting the laptop to boot first from the internal HD, it loads windows directly without reading the ubuntu HD, as it normally does and when setting the laptop to boot first from USB (i.e. the ubuntu HD connected via SATA to USB) it loads GRUB without any option for windows {i.e. I have not yet run update-grub whilst the windows HDD was connected})

I just swap between which HD to boot first from the bios, no boot manager knows about the other OS. As I have no other way of more permanently add another HD to the harddrive.

Both the unidentified partitions/disks in the attached image are ext4 partitions for the ubuntu installation.

Hi Isoya,
This is not the desired Snapshot!
1. Keep both the disks : Ubuntu & Win 7 connected, Boot into win 7, Launch PartitonWizard.exe > Disk & Partiton Management
2. Make sure the Window is enlarged & showing all the disks. Then take the snapshot.
3. Make sure the Snapshot is of good quality.

( It seems you are hesitating to say something ? Bring that out. I will take it positively. )

Thanks & Regards. ...
