I am running a computer Windows7/Ubuntu 11.10 dual bootable. Both OS installations are on the Secondary slave drive, The primary master was just for storage. I had to remove the primary master drive and afterwards I couldnt boot either OS. So i re installed Ubuntu 11.10 to the partition previously containing the Ubuntu install just to be able to start the computer. I am wondering how, if possible, to be able to boot the windows7. Ive looked into adding windows to the grub list. can someone please help? i do not want to reinstall windows and loose all important documents and files

So i am sure that the windows 7 OS is still there

Start sector 2048?
1st partition missing?

EDDY1 is right.

I believe Win7 puts the bootloader onto a separate partition so you need to recover it.
"parted" is your friend.

(very) close.
There was a partition with the Win7 loader code on the other disk (not in the first 2k of this disk).

Windows is very bad about wanting it's installation on the first disk in the system. I would assume that if you forced it to install on the second disk, it installed it's bootloader on the first disk, which you removed. In XP, the most straight forward way to fix Windows was to use your Windows DVD to boot and go into "recovery Console" and run "fixboot". Win 7 has an automated system if If remember correctly. You may be able to use your Windows disk to repair the Windows bootloader, but that will most likely mess up the booting of your Linux installation and you would then have to repair that.

The primary bootloader (not bootmgr and other peripheral windows boot files) set always in first sectors of a first primary (master) drive. When you install Grub in the same location (dev/sda), it read this date, and incorporate into itself so you get a boot menu entry in Grub and file ntldr renamed into grldr. But the first partition of the first prymary drive is removed, so any bootloader id killed.

True, it is vary easy process in Win Vista/7. But it often fails. May be need re installation of Win, without formatting partition, wit previous installation. Your old windows installation will be moved to "windows. old" folder not deleted.
You don't be worry about you data, it remains intact, if you will not remove or format partition with Windows installation. You can access to it under from Ubuntu, and copy to any safe location.

This I found on "Tweak Home PC" site:

Yes, that is the procedure I spoke of, but Arelatensis is correct when he says it does not generally work well. Hopefully it will be able to install the primary bootloader on the correct disk and your Windows installation will be back to normal. Just remember, when Windows repairs it's bootloader and the MBR of that disk, there will no longer be a link pointing the system to the grub bootloader. It will point to the Windows bootloader. So you will then have to fix your Linux installation.

Hi. No Idea if what I'm going to write will help to understand the problem, but here it is.

First, I think that installing a system on a secondary disk was a mistake, even if it worked; then, after you removed the main drive you might have tried to set the jumper of that secondary disk on "master", and still, this is of no use if the bootloader was installed on the original primary drive.

Concerning Windows, I discovered that in any case it is better to first install Windows, and then only Linux, because done otherwise Windows will erase the Linux bootloader.

Because this happened to me some time ago, I decided the best way to deal with the problem was to just reinstall everything in the correct order, on a correctly configured hard disk. I was by the way able to save first my personnal files with the help of a Linux livecd.

Best Wishes to all,
Paul

OK, so you have a Master and a Slave. Both operating systems are installed on the slave.
1. Understand that the Master is your boot drive.
2. It contains the Master Boot Record.
3. It is the Active Boot Device that is required to start GRUB.
4. With the Master removed, you have none of the above.
You might:
1. Make the Slave a Master by changing the connection port in a sata drive.
2. Change the Jumper from Slave to Master on an IDE drive.
3. Check your BIOS and make sure it is set to Master and Active if possible.
4. Re-Install GRUB on Slave and set up your Windows and Linux partitions as they do exist on the Slave.
My Recomendation:
Put back the Master and backup all your Documents, etc. to a USB or external HD.
Remove the Master and replace with the Slave.
Reinstall Linux. After all is running fine, Download Virtual box form Oracle.
Run Virtual box and once you get the installation screen, you can reinstall windows and run Windows as a virtual OS inside Linux.

Hi.
This is on the same vein but in anticipation of an endeavor.

In my dual boot systems, I agree with the previous entry: I've found it best to install Windows first, then make it a dual boot machine. I've found it always dicey to mess with the primary/secondary disks when in the mix is a brain-dead operating system such as any Microsoft offerings.

I have Windows/XP on its own machine, my second machine is dual-boot.

• Windows -- don't recall when I last used it
• SuSE
• CentOS -- my current Linux of choice.

My customer base is mostly Windows/XP, then Macintosh, then Linux, then alternative Windows:vista,7.
Both machines are old -- one's approaching a decade, the other I'm not sure doesn't have vacuum tubes.

I've decided when Windows/8 is out for a couple of months this Spring/Summer (and I have the cash-flow), that I'm getting a 64-bit machine with way too much memory and disk <.grin>
I'm getting it with Win/8 installed, when I get it home, I'll make it dual-boot CentOS. On the CentOS, I'll install VMWare so I can have differing Linuxes, either for supporting my customer base or for my own amusement and education. I can test my java development on multiple operating systems.

One of my partitions will be Win/8, so I can always have it live and I don't have to reboot to gain access.
Even though all my Win/8 work and stuff will be on my 'VM-Win8', I'll occasionally boot native and keep the 'original' up-to-date so that if I have problems, I can boot it 'native' and eliminate any accusations that the problem is related instead to CentOS or VMware, etc.

Does my plan make sense ?
Any caveats ?

Very Good Doug!

You seem to have things covered. VMware is pretty good, though I much prefer Virtual Box for its no nonsense simplicity. Once you have tried it, Ahh, well, You might agree. With virtualization, it is always best to get as much memory as possible. I saw a laptop with an AMD 4 core processor and 4 gig of ram at Walmart for about $548. All I can say is "Ham Sandwich", no bologna here. Now if only I could add raid to my laptop????
