Multiple boot images on Laptops
G'day People,
An unusual one for you. I am looking after some laptops (Toshiba, Win XP Pro on domain) that are used in a training environment with some rather specialised adaptive software. We have been having problems with various pieces of software conflicting with each other. I need to be able to use all this software on the same machines but not at the same time. What I have come up with is to have a boot manager and separate boot images and choose the image I want to use depending on which software needs to be used for the next class at boot up. This will solve the problem of the software conflicts as the conflicting software will be on separate images. That would be fine and easy, except that because it is a training environment, I was also wanting to use Ghost or something else that would actually install a fresh copy of the chosen image every time the computer is booted, copy it from one partition to the C: partition and then boot that image. I am not sure if this is possible or not. I have never heard of ghost being used in exactly this way. PCRDist perhaps? Thanks in advance for any help Craig |

I am not sure if this is possible or not. I have never heard of ghost being used in exactly this way. You have two possibilities: 1) Ghost a clone to other primary partitions on the same disk. Then, using WinXP's built-in boot manager, multi-boot to the OS of your choice. Install whatever applications you want on each clone. You will have to know how to add entries to the boot.ini file which is in the partition marked "active", though. This is the file which names the optional OSes and from which the menu options are presented at boot time. It and the loader, called ntldr, are just below the root of the file structure on each partition, and they control the multi-booting and loading procedure. If the 1st partition will always be the one managing the loading, it can be kept as the partition marked "active" and you can just maintain the boot.ini file that is there. There is one caution, though. In making clones the usual way (i.e. from drive to drive), to avoid having the clone WinXP from linking into the original WinXP upon the clone's 1st boot-up, it is customary to disconnect the original OS during that 1st boot-up. That precaution may or may not be needed when cloning from a partition to another partition having a different partition number. Try the cloning and boot-up of the clone. Then set the clone partition "active" by using Disk Management, and groom the clone's boot.ini for a boot-up. Then delete the original partition, and see if the clone still works when you boot the drive. Then report back here. 2) Ghost an image file of the bare OS to another partition. Then restore that image to the 1st partition each time you need it and then install in it the software you want. Have fun, and keep in touch. *TimDaniels* |

Some time ago I went into this problem, but I didn't understood it well. What does happen, exactly? I don't know. And it's probably a purposeful design by Microsoft to keep people from making clones of its NT-based operating systems. What you get if you're not careful is a siamese-twin OS instead of 2 independent OSes. They do work as one if they are both kept, but the clone can't be separated. How the clone recognizes that the original OS is its "parent" remains a mystery to me, but once booted in isolation from the original, the clone becomes independently bootable. (BTW, this phenomenon was 1st mentioned in this NG by "Rod Speed".) I haven't yet found the time to experiment, but I'm hoping that this recognition can be blocked if the clone and its "parent" are on differently numbered partitions. That would allow clones to be put on other partitions of the same HD. If you find out, please post it here. It does seem that the 2nd, 3rd, and 4th clones that are put on *different* HDs don't need to be isolated on their 1st bootup, but I haven't thoroughly investigated that. *TimDaniels* |

Number 2 wont work. Each of the different configurations need to be used several times each week. Number 1 is better but it still means that if a user makes any changes they will be reflected in each image and I prefer them not to be. Main reason for this is that some of this software is playing up so much that I have to give the users admin rights or it wont work properly and in that case I don't want them to be able to do anything that can't be reversed by a simple log off. I'm starting to think that is not a simple problem and that I may have to investigate PC-RDist further. From my memories of working with it a few years ago it would let me do what I need to do. Hopefully :-) Ah well back to surfing the net for info. Any further thoughts most appreciated. Thanks again Craig Powell |
