There were no registry edits. On a new build since first triple booting I decided to install each as a stand alone knowing I would eventually consider one of the new WD Green Power 1tb models for a large capacity storage drive eliminating the smaller ide model. The first board gave out in 3 days of completion requiring XP to be reinstalled and a call to MS on Vista for activation correction.
The system restore feature for both versions has never been turned off since the two were installed with XP seeing a second reinstall when for some unknown reason after not having booted into it it won't load. I forgot to unplug the ide drive and saw D for XP! Someone else here learned that as well from reviewing the thread seen in the Wiki there. :scared:
Having dug a little deeper when first hearing about the loss of restore points when dual booting Vista with a previous version I came across one good "work around" as it is labeled found at
http://vistasupport.mvps.org/preven...ng_lost_when_dual_booting_with_windows_xp.htm
The only time the Vista was unplugged a second time is when realizing that it was still plugged in when seeing D instead of the normal C drive volume. The ide drive was then unplugged for a clean stand alone installation of XP to go onto the second drive then. The Vista installation disk's repair tool was later used when Vista failed to load having been made inactive.
Since that repair was made no alterations on either version except timeout setting to hasten the bootup time of Vista and XP alike were made. The manually created restore point seen in the image earlier was the first manual point. The unchecked drives shown there apparently have been that way since last September.
With the two versions isolated you can view, copy files back and forth between drives, and actually have full access without loss of restore points. With a dual boot possible with a new drive installed and at present trying to add XP the HnS tool is the thing being looked at now in order to preserve Vista's restore points other then following the information seen in the artcle at the link there.
In reviews of the information posted here both drives set apart without a dual boot configuration seems to protect both versions from each other simply seeig the other version's drive as a logical drive not a different version of Windows being detected as well as installed and configured as would Vista adding XP or adding XP to Vista with XP of course canceling out Vista's restore points. Most will obviously prefer a dual boot over seeing each installed totally separate with the use of a boot device menu or boot order change with constant trips into the bios itself.
