Solve : Windows 7 or Vista on USB drive? External HDD??

Answer»

I currently have Ubuntu installed on my HDD, but I also want Windows (preferably 7) so I can run software and programs that aren't compatible with Linux. Can I put Windows on a USB jump drive or an external HDD? (CD is not an option, because I only have 1 CD drive and need it for something else)
Are there any other [external] options?
I'm hesitant to dual-partition, I'd much rather put Windows on an external device. However, if dual partitioning is my only option, I have 2 additional questions: How much will it slow down my computer (to have 2 OS versus 1)? And will I need to delete my Ubuntu partition (currently taking up entire HDD) and reinstall it in a smaller partition, or can I shrink it without losing data?
I do not want to install Windows within Ubuntu. If I dual partition I want to make the partitions completely separate.

Thanks for any answers.You should only consider having a HIGHER RAM for your machine. And maybe a 7200 rpm large capacity hard drive is better for having 2 OS installed(patition) on one HD. Or maybe you could post your current computer specs.

No. Windows is designed to be installed on an internal fixed drive.

It would not "slow down" your computer at all.

You can shrink it.

You cannot do this anyway.

I know Ubuntu can be installed within Windows, I didn't know if it works the other way. Thanks for telling me.May not be suitable for you but there is the option to put XP on a flash stick...I did this in a very similar situation

Have you heard of Wine? It can run a lot of Windows programs.

Check out the Wine HQ app database to see if the programs you want to run will work WELL with Wine or not.

Why not?
You can use a virtualization program like VIRTUALBOX to run it in a virtual machine.

You can delete it or shrink it, whichever you prefer.

You should alway back up your data before doing any partition editing.
You will need to boot to an Ubuntu live CD in order to shrink your partition. You can't resize a mounted partition so you will need the live CD. Once you've booted the CD, go to System > Administration > Partition Editor. This will start the Gnome partition editor.

To resize your partition, right-click it and select Resize/Move. Then you can adjust the size of your partition using the slider or you can input the size in the boxes below. After you shrink it you will see a gray portion listed as unallocated. You can leave it unallocated. When you boot the windows DISK you can create and a format a new partition in the unallocated space. If you see another partition called linux-swap leave it alone. None of the resizing actually starts until you click Apply so you can play around with the sizes until you get it where you want.

Also, if you install windows after Linux, Windows will ovewrite the master boot record. See here for how to recover grub.

If you want to delete your Ubuntu partition and start fresh, you can boot the windows CD and delete it. Then you create a new partition for windows and install it. Once you have windows installed you can then install Ubuntu after Windows which is slightly easier.

It won't slow it down.
