Vista on one HD, XP on another - possible?

by humax1 / March 2, 2009 9:33 PM PST

Hi,

I just bought the Lenovo 3000 that Tiger Direct has on sale for $220. It came with Vista Home preloaded, no CD. This is replacement for an older, non-working Compaq with XP. The HD on the Compaq still works. I don't think I received an XP CD either when I bought the Compaq.

Is it possible for me to install the Compaq HD as a slave on the Lenovo, for extra storage and to boot up XP in the event I need to run a program that is incompatible with Vista? If yes, what is the procedure to make it boot XP? I have seen some threads about dual booting, but they all seem to require a Vista CD.

Thanks for any help,
h

It is possible to have Windows Vista on one drive and Windows XP on another, and it is possible you you to reuse that old drive as a slave in the new computer. However, the old copy of Windows XP is locked to the old computer, technically and legally. Thus, you would need to buy a new licensed copy of Windows XP for it to work.

What about a new copy of XP?

Thanks for the reply. If I buy a new copy of Windows, what then? I've seen some posts about Vista getting overwritten when XP was installed. That would be a disaster, as my computer did not come with a Vista installation disk.

It is not an overwrite...
by John.Wilkinson / March 3, 2009 10:35 AM PST

Windows XP overwrites Windows Vista if and only if you tell it to install itself on the same partition as Windows Vista is on. Install to different partitions and Windows Vista remains intact. However, Windows XP's NTLDR will overwrite Windows Vista's Windows Boot Manager, an issue you must use VistaBootPRO (no longer free; majorgeeks.com currently has a free download) or EasyBCD (still free) to resolve by forcibly restoring the Windows Vista boot loader.

Sounds complicated

So, these are the steps: get a fresh copy of XP, install it on the second HD, then Vista won't work on the first HD because the XP install overwrites the Vista Boot Manager, so reinstall the Vista Boot Manager with VistaBootPro or EasyBCD?

I assume the reinstall of the Vista Boot Manager does not overwrite XP's NTLDR?

The fact that I have a legal copy of Vista on the computer does not entitle me to a restore CD or other support from Microsoft?

Thanks for the replies, seems this is more complicated than I had hoped. What if I install Ubuntu on the second HD -- same types of issues?

-> Yes, that is an accurate summary.


I assume the reinstall of the Vista Boot Manager does not overwrite XP's NTLDR?
-> Correct. Windows Vista's Windows Boot Manager will be default, but leave NTLDR in place and hand control over to it whenever you select "Previous Version of Windows" from the boot menu.


The fact that I have a legal copy of Vista on the computer does not entitle me to a restore CD or other support from Microsoft?
-> Unfortunately correct as well. A preinstalled OEM copy is sold to HP, Dell, etc at a reduced cost, reflected in the price of your computer, due to HP, Dell, etc accepting full responsibility for all support. You can order/burn a 'system recovery' DVD, but not a Windows Vista DVD and you cannot receive free Microsoft support. (Windows Update is the exception.)


What if I install Ubuntu on the second HD -- same types of issues?
-> Actually, no. Ubuntu's GRUB boot loader will automatically take over, leaving any/all Windows boot loaders intact.


Hope this helps,
John

Thanks much, John. Guess it is not worth it to buy a new copy of XP unless I run into a major incompatibility issue with Vista. Maybe just for fun I'll put Ubuntu on the second HD, to see what it can do.

Check your BIOS

I can choose Setup when my computer boots and boot from either of my two hard drives.

I turn one on and one off.

XP is on one and Vista is on the other.

I still think Vista is essentially useless and boot to XP 99 percent of the time.

I may replace Vista with Windows 7 assuming my son, who works for Microsoft, can get me a copy for $35 or so.

If you do go the BIOS-based dual-boot setup, remember to disconnect the one hard drive before installing Windows XP. Otherwise NTLDR will still overwrite Windows Vista's Windows Boot Manager.

If I install a new OS on the second HD, do I still set the jumper to Slave? If the HD sometimes boots the computer, is it still a slave?

Thanks,

The rules for jumper settings
by R. Proffitt Forum moderator / March 5, 2009 1:01 AM PST
In reply to: one more question

Vary with the drives, the IDE cable used and so no one can make a simple statement to use what jumper without knowing the machine, cable type and the hard disks.

The rules for setting jumpers are fairly simple to follow but you can't do it without the details.

The easiest way...

Is to set the CS (Cable Select) jumper on both drives, letting the system determine which should be slave and which should be master.
