    hello mates, I'm a newcomer here, I have an ASUS laptop whose CD player has a hard time reading CDs, at the attempt to fix this issue following an online guide I accidentally deleted from the registry both upper and lower filters, now not only is the DVD player unable to read disks, both the pointer and the keyboard are irremediably stuck! it's the same problem as the following:

    http://forums.techguy.org/windows-nt-2000-xp/798898-solved-xp-pro-sp3-frozen.html

    this user said to have fixed it but didn't quite explain what he exactly did, my boot sequence is set to start from the CD player but since it has trouble to read disks I'm unable to boot the xp CD, the only working things are USB ports, can anybody help me please? I'm desperate and need the data in my laptop

    If the CD drive doesn't work during the boot process, then you're dealing with hardware failure.

    Have you yet tried the "Last Known Good Configuration" option in the safe mode menu ? So your keyboard should function during the POST of your boot before loading windows, so you can hit the key to get into the; "Advanced Options Menu"

    You can change your BIOS boot order so that removable devices (USB), is first, and or use the F key for the boot menu, so you can boot to either a bootable USB flash drive, such as one with live Linux, or the www.ubcd4win.com , or a external USB DVD/ CD ROM drive with your XP CD in it to edit the registry correctly. The upper and lower filters need to be in there as values for each of your devices, (keyboard, mouse, CD-ROM), with the value data must be matching to the name of each device driver, without the file extension. For example with the keyboard the filters value data is; kbdclass. This registry key is found; HKLM\System\ and then; Current Control Set\Control\Class. Then you just click on each sub-key to look for the right devices to edit correctly.

    the pen is already formatted as FAT16, the right file to download you mentioned is UBCDwin.exe?

    I followed all the instructions reoported here http://www.pendrivelinux.com/install-and-boot-ultimate-boot-cd-ubcd-from-a-usb-device/ now all the stuff was successfully extracted into my USB pen formatted as FAT32, but it still won't boot, all I can tell you is that my USB pen is listed on the bios under the CD/DVD drive, and I set it as the max priority boot, but I had no luck yet, what's wrong? should I activate some hidden thing from the Bios? or even worse update it?

    Some BIOS do have an option called; enable legacy USB, so check if your's does, and then do enable that which allows full USB functions prior to the operating system. That USB flash dirve UBCD4WIN version needs to have the .iso file created first using your XP CD SP2 or 3 and the downloaded UBCD4WIN.exe program, see; http://ubcd4win.com/howto.htm . You need to do this process to create the .iso file from your own XP CD due to legal license issues. But that link I gave you from Pendrive Linux is only the plain text UBCD version. And that other version as; UBCD4WIN is a fully graphical live CD version of XP windows, which is has more process to create, but is better to boot to and use the tools on it. And when you run that .bat file at the end of the process, it is run from in your USB flash drive to make it then bootable. Here is a thread which had a keyboard only issue, and I used the on screen display, (Accessories, Accessibility), type of keyboard with my mouse; http://forums.techguy.org/windows-nt-2000-xp/805806-solved-keyboard-driver-missing-corrupt.html

    as I told you via PM the bios does see the USB pen, when the asus logo appears during the boot I press esc for the popup menu, there it asks me where I want to boot from, there are 3 options:

    1. hard drive
    2. DVD
    3. USB pen (it also sees the brand of the pen)

    I choose 3 but nothing happenes, after a couple of secs of black screen the windows logo appears.

    the operetion I followed from this link http://www.pendrivelinux.com/install-and-boot-ultimate-boot-cd-ubcd-from-a-usb-device/ at the end of it asks me to click any key in order to make the pen bootable, but when I click a random key it says "parameter incorrect, something went wrong"

    at this point I think my bios is all set for booting from USB, I just need to find the right bootable software to put into the pen, USB mouse won't work either unfortunately, maybe a USB DVD player would do the trick but I don't even know who I can borrow it from, all I have to do is reparing/raplace the registry but I got into a situation.ò

    The XP Recovery Console can be used to replace the system registry files, but this will make it as it was from a fresh install, so any setting changes or programs are lost. Here is the site; http://support.microsoft.com/default.aspx?scid=kb;en-us;307545 , and this one here too; http://support.microsoft.com/default.aspx?scid=kb;EN-US;307654 , but you need to be able to boot to your XP CD disc. With that UBCD you may have access to your XP folders and files with the File System Tools, but your system condition may require either a repair re-install, or a fresh full re-install from your XP CD if you can get a working CD/ROM. But if you creat that other full graphical live XP version which is the UBCD4WIN, it does have several registry tools to use; http://ubcd4win.com/contents.htm

    I created the iso of the xp version which has the registry tool and replaced the linux one in the UCBC folder with it and repeat the process (clicked fixubcd2) but this time it gives me a kernel error when I boot from the pen

    I made it, with ultimate boot cd for windows and an external hard drive that I borrowed I managed to restore the registry to a previous checkpoint, now everything is back to normal, thank you for suggesting this great software :)
