  1. Usb Boot "Offline Nt Password & Registry Editor"

    Posted 5 Oct 2010

    I found an update for the "Offline NT Password & Registry Editor" by PNordahl. (This item is included in UBCD4Win.) I copied the updated files into UBCD4Win v3.60 and built a CD, generating the ISO image and everything works fine. I was able to use the BootCD to boot on a Windows 7 64-bit laptop and successfully reset the local administrator password.

    So I then ran the UBUSB.EXE utility that comes with UBCD4Win to make a bootable thumb drive. We use the bootable USB thumbdrive all the time and it works very well. After running the UBUSB.EXE and having it format the thumbdrive and copy all the file, it all worked fine and copied the "Offline NT Password & Registry Editor" files into a \isolinux folder. Since I'm using Grub4dos on the thumbdrive when it's made, I need to edit the "menu.lst" file to add the entry to boot this item up. However, I can't get the syntax to work so it boots properly and am hoping for some help.

    Basically I got to a point where the Offline NT Password & Registry Editor to boots up, but it doesn't seem to load any mass storage drivers, so it can't see any hard drives or partitions.

    Looking in the syslinux.cfg file for this, you see:
      MENU LABEL Offline Password & Registry Editor
      * version: 2010-06-27
      * http://pogostick.net/~pnh/
      Petter Nordahl's Offline NT Password & Registry Editor
      KERNEL /isolinux/pnordahl 
      APPEND rw vga=1 init=/linuxrc initrd=/isolinux/pnordahl.

    My understanding is the last two lines above are important to "convert" to grub4dos format. Looking at other examples, I came up with this for the menu.lst in grub4dos:
    title Offline Password & Registry Editor
    kernel /isolinux/pnordahl rw vga=1 init=/linuxrc
    initrd /isolinux/pnordahl.cgz,/isolinux/

    This fails, telling me the file isn't found. I assume it's the "initrd" line since it is referencing more than one file there with the comma splitting the two items.

    So I changed this to be this:
    title Offline Password & Registry Editor
    kernel /isolinux/pnordahl rw vga=1 init=/linuxrc
    initrd /isolinux/pnordahl.cgz

    This actually boots up, but it gets to a point where it scans for hard drives and can't find any. I assume this is due to me removing the "scsi.cgz" info.

    Basically I don't really know what I'm doing and am hoping someone here has previously done this and can share the contents of their grub4dos menu entry for booting this Offline Password & Registry Editor. Can anyone help?

    Thank you.
  2. 802.1x authentication for "wired" connection?

    Posted 1 Jul 2009

    I apologize for not being more educated or informed on this, but this isn't an area I work with, but I do make the BootCD for our group. Regardless, in our organization, (state government), I had a meeting that our Wide Area Networking group wants to enable 802.1x authentication for the "wired" network to enhance security to prevent having just any device plug into the wired network and get an IP address.

    Obviously my first concern was with the UBCD4Win BootCD that I've created the past few years that all of our techs use.

    From what I can gather, if/when they enable this on our switches, when we boot up with the BootCD, we won't be able to actually get on the network.

    It sounds like on a normal Windows XP workstation, you have to also start the "Wired AutoConfig" service. But this service doesn't appear to exist in the BootCD. (Is there a way to add this?)

    Has anyone dealt with the BootCD in this scenario before and have any words of wisdom? From my searching in the forums and on the internet, this isn't a topic that seems to come up anywhere, so I'm hoping for some help!

  3. GParted plugin

    Posted 15 May 2008

    I'm going to refresh our boot cd that we use. I've always included GParted as part of this. I see there is a newer version of GParted out than what I last used, however, the directory structure inside the .iso file is completely different now with different files. The newer versions have completely changed the files and folders inside the .iso, so I have no idea what to copy out of them and looking at the plugin, it seems it would not work due to the files and folders being different now.

    In the past I'd extract the gparted.dat file, etc. to my multiboot plugin folder. But that file (and other files/folders) no longer exists inside the .iso. I'm guessing the current plugin I use will no longer work with the newer version of GParted, so I thought I'd ask here if anyone has an updated plugin (or info) to make the newer version work?

    The last version I used was the "gparted-livecd-0.3.4- 11.iso" file. The latest stable and test livecd's are "gparted-live-0.3.6-7. iso" and "gparted-live-0.3.7-2. iso".

    Thank you for any help.
  4. Create automatic drive recovery CD?

    Posted 12 Apr 2008

    I've been told that we may have a project to give out older computers to disadvantaged children. I've been tasked with creating a clone image to put on these computers. That part should not be a problem, but I've also been asked to look at creating some sort of "auto-recovery" CD. These computers will only have CD drives and not DVD drives, so that complicates things a bit since I'm positive the clone image will not fit on a single CD and will need to span multiple CD's.

    Basically I need to create an bootable CD that will boot up and automatically start a 'restore' of a clone image to the hard drive. This restore, would obviously need to "prompt" to put in the other CD's for the othe parts of the clone image. They want to include this recovery CD with each computer to make it easy for these families to restore their computer if needed. I've done lots of cloning and making bootable CD's, but I've not done anything like this recovery project and I'm a bit stumped at the moment. Obviously this has to use a "free" disk imaging program. I can't just include a copy of our corporate version of Symantec Ghost to do the restore. This is where I'm running into a problem.

    Has anyone else done a simliar project and if so, can you offer some suggestions on how to accomplish this? I've been looking at some of the free drive imaging programs, but I've yet to figure out how to automate a clone image restore with these programs, especially when the image will span multiple CD's.

    Thanks for any advice.
  5. Drivers "insufficient memory" error

    Posted 17 Apr 2007

    I'm not bringing this issue back to life to rehash or find a solution, but rather to raise a question about the future path of drivers in this project.

    In our organization, I had made an updated v3.04 UBCD4Win BootCD using LittlBUGer's "2.0" drivers pack. On at least two different model computers with 512MB, we got the 'insufficient memory' error. When we bumped up the memory to 1GB in these pc's, the memory error went away and things booted fine.

    To attempt to correct this, I used the 'Net' drivers from the 2.0 pack and the 'SCSIAdapters' drivers from the 1.9 pack and still got the memory error. I then deleted 2 driver folders from the SCSIAdapter folders and then the boot cd booted fine on those 2 pc's with 512MB RAM.

    However, using that boot cd on 2 machines with 256MB of RAM and within Virtual PC 2004 configured with 256MB of RAM, I got the insufficient memory error on one of the two computers and inside of VPC 2004. (For our organization, for the forseeable future, it's necessary for the boot cd to work on pc's with 256MB of RAM since we have a great many of these still in use.)

    I then remade the CD completely going back to the 1.9 drivers. (I manually updated a few of them with newer versions, but I did not add any additional drivers that weren't included in the 1.9 pack.) This CD, which uses the 3.04 project and the 1.9 drivers packs boots fine in VPC 2004 with 256MB of RAM and it also booted fine on the 2 machines with 256MB of RAM.

    Initially I was of the thinking the memory issue was due to some conflict with drivers or something with the 3.04 version of the project that was different than the 3.03 version. However, after looking at things, my thinking now is this memory error may have something to do with the 'total' number of drivers used. I say this because with either bumping up the RAM or reducing the total number of drivers being loaded, the problem went away.

    I know that the BTS Driverpacks are the apparent future of this project for drivers, but my question is if there really is something to the total number of drivers causing this problem, will it show up someday with the BTS pack when they get more and more drivers added? And if so, how do we 'thin out' the number of drivers we need? Looking at the BTS Mass Storage driver pack, I can't figure out how to remove drivers from it if I ever needed to reduce the total number of drivers. With the 1.9/2.0 drivers pack, you simply delete the folder the driver is in.

    I don't know that the BTS packs will have this issue or that I'm accurate with my thinking regarding this memory issue may be due to the total number of driver. But I wanted to post something with my results and to at least put this info out there for future reference if someday we get to using many more of the BTS packs and suddenly we get insufficient memory errors showing up. Hopefully this is not the case though.
