solution is try to re install the Windows Vista back and see whether the TPM will show missing. sometimes thats happening to most of the systems. when you try to put another windows thats did not came with the product, you will miss some functions such as drivers, battery not charging, internet not working, audio not working and many more. so put back windows vista and whether your problem still existing.

Upgrading windows vista to windows xp in presario 115DX


You cannot 'upgrade' Windows Vista to Windows XP - that is technically a 'downgrade' and would need you to save all your user data on Vista then format you Windows drive then do a clean install of Windows XP.

If you try to install XP over the top of Vista you will have lots of problems because of the difference in architecture and boot manager changes.

The only alternative would be to set up a dual-boot installation where you install XP alongside Vista but would be best done on either a separate disk partition or on a second disk. Normally such a dual-boot configuration would start with having XP installed then adding Vista as the second operating system.

Install xp on sony series nr


The BIOS doesn't care nor detect the installed OS and should only be upgraded if you are having BIOS issues.

The old adage "If it works don't try to fix it" certainly applies here.

Windows Vista


hi there
There is 2 ways to do this, firstly you can create a floppy disk with the updated bios flash file on ( not recommended to a novice ) or reinstall XP and updated the bios by downloading it from the manufacturers website and installing it that way. After that you can install Vista.

good luck

Does the fj270 recovery disk from ebay make the computer like new with a blank harddrive?


I am assuming you are going back to XP?
You will run into one major problem with this process, Vista is based of Windows NT which uses a NTFS file system. XP uses the old file system of FAT32, so just wiping the hard drive probably won't work. You will have to go into your partition and re-partition your hard drive before you intall the recovery disk.
If the recovery disk is designed for your computer then yes it will restore it to all factory defaults (including drivers and software that originally came with it.
If you are not sure how to do the partition then let me know I will try to guide you through it.
