Unable to uninstall Vista & install XP

May 6, 2009 at 14:48:19
Specs: Windows Vista

My HP came with Vista, which I want to revert to a legit copy of Win XP. When I attempt this, I get a blue screen after all the drivers load during installation from the XP CD. I have read that certain HP computers will not allow XP on certain PCs....can anyone verify if this is true or help me please

Make sure the hard drive is set to legacy/IDE mode in the bios (it will almost certainly be a SATA drive, and if in AHCI mode could cause your problem).

If that's not it, is the blue screen before the part of the install where you choose where to install? If its after this, did you remove all existing partitions before creating a new one for XP? (you need to do this).

There's no reason I can think of why XP wouldn't install - though there might not be XP drivers for all the hardware (hint - does the HP site have XP drivers for your model). If no XP drivers on HP site, then you could have a job chasing them down from individual manufacturer's sites, if you do get the install to work (though I have successfully managed this for a couple of machines - took some googling!)

I'm assuming that vista worked (ie, you haven't got some duff hardware in there)

HI - I don't have a link....but in browsing numerous forums I've seen a number of comments to that effect. Apparently there are either bios or motherboard issues/conflicts that HP intentionally created....and that is not right to be forced to use an operating system you don't want. I think Vista needs a huge amount of work to be what WinXP already is with the service pack II. Still hoping to find a way to install it and dump Vista. If you have any suggestions, please post! Thanks!

can you post your exact HP model, and I'll check it out.

btw - have you actually gone into the bios to check what I suggested (think the Esc key while booting is common access method on current HP laptops, but it should tell you onscreen before anything else) - I've seen the AHCI setting for SATA drives cause bluescreens for XP installs several times (including an HP 6735s laptop which I've just this week procured for a customer - taking Vista off and putting XP on)

Thanks for the suggestions. I have not had time to ck the bios setting...and I would need to know exactly what to change, if that is what is needed. My HP pavilion model is: a6400f.

As for drivers, I have virtually everything needed that Vista already has....Ethernet, sound card, etc. as I did the install of XP on another PC that easily allowed it. If you can walk me thru this process in a post, it would truly be appreciated. Thanks!

HP do not supply XP drivers, but check out http://forums.driverguide.com/showt... - last post has links to (some) XP drivers. Plus advice like using everest to determine which hardware you have is exactly what I use.

I'm pretty sure the SATA mode is the reason for not being able to install. Different bioses word it differently, calling it IDE mode or legacy mode for example, but you should access the bios settings and check out those for SATA/RAID.

That thread I linked doesn't include graphics (unless they're included in the chipset, which they might be) but being intel, you should be able to find.

So I'd check/change bios setting, run install again. Download those drivers & install when XP up. Any missing, you can get good idea from the Vista driver page:-

or use something like everest
