HI Bernie

There are other options: I’m assuming you’re using Windows, but before you do, can you explain what the Bios problem is, as it may be fixable.

1. Install your old drive in the new computer , then when it boots up the new OS will recognise it and assign it a drive letter, thus you can leave all your data in situ and just access it whenever you want.

2. Providing the Bios in your new computer has similar HDD settings as your old computer, you can tell it to boot from your old drive, (Make sure you have the driver disc for your new computer in the DVD drive) then when it boots your old OS, everything should be there and the new drivers will install as required.
When the system re-boots you should then be able to use it like your old computer but with better performance. (Note you will need to re-activate the OS by calling Microsoft, however it is a Freephone number (Details will come up on screen, just tell them you have had to change the HDD) and all should be well)

You can switch between the new an old OS by going into the Bios and choosing which HDD to boot from.

NOTE: In most cases the above will work without problems, and hopefully yours will not be one of the few that won’t.

If you’re not sure any decent computer repair shop should be able to do it for you.

Hope this helps
