Pls....pls....pls....help...

this is BSOD oo, probably some thing happen in your hardware issues

how to solve bro...pls help...

You have to remove Vista folders before you install XP directly. There are some security lockups for Vista folders and you have to unlock them using Vista before you install XP.

ATM i still can use the vista oc right know....so how do i need to remove the vista folder bro....

try to do with full format process ebfore installing the wind xp?

format your hdd before reinstall xp, cause window doesnt allow downgrading.

There is a lot of work to do to unlock Vista folders. Use explorer and right click on Windows folder for the properties. Then

Security tab > Advanced > Owner tab > Edit > Other users or groups...

Type everyone and hit check names then click ok then apply. Then right click on Windows folder for the properties again and go to

Security tab > Advanced > Auditing > Add

Type everyone and hit check names then check Full Control and click ok.

Then right click on Windows folder for the properties for again and go

Security tab > Advanced > Permissions > Edit > Add

Type everyone and hit check names then check Full Control and click ok.

Then right click on Windows folder for the properties for the last time and go

Security tab > Edit > Add

Type everyone and hit check names then click ok. Click on full control and you are done with this folder.

Do the same thing for Program Files(don't forget Program Files (x86) if you install x64 edition), Documents and Settings and Users folder.

Edit: Don't do this for fun, it will compromise the security of your Windows

will try when back home....working right know...hope this can be settle tonight...

I never tried installing XP on Vista partition directly but you may have to delete Vista folders if you can't install XP. The files on the Vista folders are newer and it could affect the xp installation. Get or make a bartpe cd and use the file manager to delete them.

The easiest way is to backup your data and format as it is faster.

i oledi trasfer all the data to my current rig right know...BTW what is "bartpe cd"...

It's a bootable cd that you can use it for recovery.

Edit: You can ignore the format if you have tons of data that may take a long time to backup. Don't forget to disable the System Restore to get rid of the junk before you install XP.

looks like hard drive kong

I know whats wrong with your windows.Original windows XP does not come with SATA driver.Go to your laptop bios and see under advanced option.Disable the SATA option for harddrive and use IDE.If can't find under advanced option,just go around the bios till you find the option to disable SATA drive

There you are done.Guarantee can install Windows XP now

Only vista setup comes with the SATA driver.

I think you need to read the first post.

dun worry all data had transfer to my 750gb SG d no worry one...

thk for the another solution bro...will check and try for it....

I don't think it's the SATA issue since you installed XP before Vista.

I know cause I have similar problems before with my newly bought Compaq C700 which comes with FreeDos.Sometimes,you can get through the setup without problem and sometimes it fails

It's possible for improper/missing SATA kernel driver which is not provided by Windows XP by default. The SATA driver is provided by chipset manufacturer like Intel Storage Matrix driver.

You can't install this driver after you have finished XP installation. It won't work that way and may cause BSOD. You need to install this SATA kernel driver during XP setup in F6 mode (Driver setup mode). You need to prepare a floppy disk or a thumbdrive with the driver from Drive A: for you to retrieve the driver in Windows XP F6 Setup mode.

Another way to do this without going through the Windows XP Setup F6 mode is by slip-streaming a custom Windows XP setup with the SATA driver.

bro, u said know the causus but you js stated sometime can get through sometime cant~

i think this is not a solution man

From what I read, TS tried to install XP on Vista partition without formatting. The Vista folders are locked with it's security features which is why he gets BSOD.

a lot issue cause this code

Well fren...I think u should check it 1st whether ur hdd is Ide or sata type..as per previous member advise..
If Sata ur must get the Sata driver 1st..then there is a step to do it..
If IDE type..maybe some of your hardware had problem..

My point of view, definitely SATA drivers.
Previously installed drivers in XP or Vista will not work in this DOS installation mode.

You'll need to get the correct SATA preinstall drivers and then
install the driver from floppy by pressing F5 during installation
or slipstream it into your XP installation using something like nLite.

bro oledi did...but problem still appear at 1st post....haiz...

this acer 4520 is using pata/ide HDD...so what seems to be the hardware problemo bro....

You have to delete those folders before you do a direct install of XP I guess. It's probably XP setup didn't replace the newer files that comes with Vista and couldn't run it properly or you can reformat since you already backup the data.

Personally I don't think it is a sata driver problem, if the windows couldn't found the hdd, the windows will state drive not found.

Windows can still detect a SATA drive even without a proper SATA driver but it assumes the drive in IDE/non-SATA mode (the default HDD detection mode in Windows XP since it could not provide a specific SATA driver.)

are u sure the windows can detect the sata drive by default? I mean for those newest chipset.

REinstalling XP from bios should work just fine.
I installed linux on my pc, got prob, wanted to reinstall xp but couldn't.
Then i tried installation from bios level, and it worked just fine.

Yes, because the PATA standard allows fallback to IDE/non-SATA mode. This fallback or IDE emulation (legacy) mode is detectable in Windows XP.

ok bro all...as i oledi tried all method that u all advice me...but still fail...from that i's suspecting something d...last i called acer support centre at kl and want them to assist me on this lappy problem...after that still cant resolve the problemo...the technician telling me that, the lappy facing a hardware problem as i expected...so tomolo will send to acer office for RMA purpose...luckily kuantan got one acer support...wish me luck for arguement...

After settle it..plz don't forget to mention ur solution to solve this prblm bro..maybe someone can refer it too..I also wanna to know what is actually happen..

what are you trying to say here.I say this because I have two identical laptop with FreeDOS and both are factory configured default to run with SATA mode ON.I successfully installed XP in one without problem but the other laptop gave me the BSOD like what TS has and I found out it is because of the SATA MODE

You don't have anything to contribute please don't reply here cause its not helping anyone here

heloo to all sifus and gurus....my problemo settle d i'm suppose to go to acer office tomolo...but need to cxxl due to i oledi manage to rectify myself....
