i have been using win 7 for the past few days and now i switch back to xp and i leave my com on over the nite and when i woke up n go to my com i see a BSODi hide my partitions using acronis disk director when using individual OS

Acronis Disk Director may be the cause of the problem. There have been reports of it in the forums causing issues. Most specifically, if you create a partition with DD, Windows 7 can't make heads or tails of it.

but its the win xp that crashes , not win 7

When Win7 installs, it often creates a large partition, AND a 100MB partition for the (win7)VistaNTboot stuff. It is the 100MB partition that needs to be hidden, NOT the larger Win7 partition. So presuming you hide the 100mb partition, and unhide the XP partition and boot, well, then XP would have to be on a different drive from Win7 and the 100mb partition, because the HD's MBR will still be pointing to the active 100mb partition. unless you mark the XP partition active before you hide the 100mb partition. (theoretically you shouldn't have to hide the little partition if you mark the XP poartition active, and you can probably get away with it - it being XP. Butyou couldn't if it was Vista (6.1). Assuming all that, how long does it take XP to crash? If it's "overnight", it could be anything - power spike, PSU glitch, mobo hickup....... I don't think there's anything wrong with Acronis DD10, but when i do that, I have win7 and the attendant small active partition, on a Different spindle, from the other opsys.Kris

Kris +1 and propose, because, shoot, I'd hire you for just being able to talk like that.Butthe original post tells me that however they did it, they successfully booted into XP, but later on, XP wanted to do something. What was it trying to do? What version XP? (sp2, sp3,??) Really old guys have been told never to use boot managers or ahci, so it's become a superstition (dunno why but why try?),?So the next question becomes a little more important, If you had to reinstall both OS's, could you, would you be willing to use Bcdedit as a boot manager instead of disk director?

woah thats alot of replies and some i do not understand at all1. i do not see any 100MB partition.2. i am running win xp SP3 ( now my internet keeps dc just like how it would in win 7)3.i now removed win 7 and did a fixmbr and fixboot in xp recovery console for xp just in case. Now waiting for BSOD to happen againok let me describe how i install my win 71. i first hide my xp partition hd0partition02. install win 7 (sata controller in RAID mode, but hdd notdoing RAID)3. create a 150GB partition and install it there4. everything went smoothly (win 7 internet keep dc after 10mins so i decided to change back)5. hide win 7 partition and unhide xp and set xp as active6. change sata back to ahci mode and everything loaded properly (used it to check some things for awhile b4 i went to slp)7. woke up and saw a BSOD

it happened againit is reported as hardware errorerror came out as: IRQL_NOT_LESS_OR_EQUALtechnical error is STOP:0x0000000A

it happened again it is reported as hardware error error came out as: IRQL_NOT_LESS_OR_EQUAL technical error is STOP:0x0000000A Thanks for great description of how you installed it! That helps! Yes, it will not always create the 100 or 200mb partition (Win explorer won't see it, but DD certainly will!) - It just puts the (win7) Vista type boot info on the opsys partition in a folder called c:\boot . This error is most likely a memory error. i get them when I overclock. I also get them on this mobo when I try to use 4GB memory - I assume it is simply a mobo problem and only run my 2 1gb sticks on this board. (I am currently using a Gigabuyte GA EP45 UD3P mobo and OCZ 1150 memory sticks)(a mobo replacement is on my list!) I found various things will produce it, even though Win7 may seem to run fine - software like roboform seems to access more memory and will cause an instant BSOD if I have 4GB, or OC this board too high. I have seen it also instantly terminate firefox, and cause a recurring termination. it is not Roboform's problem - it is simply that Roboform accesses a chunk of memory that others don't, and this causes the problem. In rare cases this might result from a cpu error, or North Bridge error, but again - all signs point to memory. Your internet could well be disconnecting for the same reason - a memory problem that doesn't cause a BSOD, but causes the LAN driver to lock. Hope this helps a tad! Kris

Kris thanks for the detailed reply but i do not quite get it....could you tell me in more simple words on what can i do or what should i do now?

Sure! Do you overclock at all? Is this new memory or motherboard or have you had it for a while? Is this a system that you can power off open the box and wiggle the memory in its socket a bit to preclude connection errors? Let's start there!Kris

my system is 2 yrs old and yes i ocmy system runs the oc speeds 24/7 for 2 yrs alrdy so i dun think it affects and my speed are not up by alot when i do 24/7i using C2D E6300 (1.86ghz @ 2.45ghz - 350x7 max) and 667 rams running at 700mhzeverysingle app is running fineyup i can power offu wan me to switch ram slots?btw i am backing up my data now and i might be cloning a clean image back if BSOD still persist... but the dc has been dropping more than 5 times alrdy

First I would pop the box and wiggle the mem sticks in their slots (power off and plug removed, of course). Removing and re-seating the sticks would be better. As to changing the slots, I would advise against it as I have seen too many mobos where the second pair of slots does not clock as high as the first. This is a mobo design flaw rather than a south bridge flaw. Then try again and see if joy / no joy. If no joy, then, yes, of course, I am going to ask you to set the clocking to mobo default and then try again. This has to be done. Sorry. Let us know what you get! Thanks so much for your cooperation on this problem!Kris

ok thanks.....i will execute....my com hasnt get the BSOD for some time alrdy... i think it would be striking anytime soon

jus another concern.....does it has anything to do wif the NIC...cos if not, no point trying

i just took out and put in....but i swap the placing(hope it didnt matter) and when it went into windows, while loading the startup apps, it says a windows just recovered from a system error and it has the send or dont send button...wad does it mean

Theyre asking if you overclock, and I want to just say I admire you for doing as much as you have done!1. Many people have had trouble with xp (all versions) and ahci.2. overclocking rules but don't do it right this second.3. The code you gave helps a lot, 4. It's not hard to check your memory, don't assume it's bad, check it first using software.5. overclocking on some computers overclocks the PCI bus, and so peripheral cards.6.You need to google your chipset and AHCI.7. This is no longer Win7 related, it has more to do with hardware (I think).http://www.velocityreviews.com/forums/t494041-cant-install-xp64please-help.html

i am not sure did i mention, i am only using 2 GB of ram 2x1GB

after doing some more reading with the links provided, i think MS has no support for AHCI for all x64 OSesBUT this is only what i think. it may not be true.why i say so?1. this situation happens only when there is a x64 OS or on a same HDD as other OS2. my xp can run wif AHCI and my HP laptop running vista home premium 32bit comes with AHCI enabledbut of cos i dunno does this have a link to the BSOD i am encountering....

Changing AHCI to anything else (or raid to standard or standard to AHCI) *Can* mess things up. The more you do the worse it gets.I defer to Kris, they are more experienced. Sorry I wasn't able to be more helpful

i did a google and they said RAID is more flexible in the sense its half AHCI and legacy

ok up till now still havent crash and internet does not dc anymore....i hope this is a sign of gd news....i am going to slp....see does it happen overnite again or not

See what happens if you do a clear CMOS and then boot into XP, after setting all the appropriate stuff in the BIOS. If you have raid set in BIOS, and are not using it in opsys, I would shut it off. For now, use IDE - NOT ahci, in BIOS Okay - so "something changed while you were running Win7". one or more of the BIOS CMOS blocks could have been modified. Something got stressed, and your OC no longer works. This does indeed happen.Kris

ok thanks for all the steps....i only took the rams out and put it back and everything was back to normal alrdy....many thanks to kris =)btw i havent changed anything in bios so o/c still running and sata in ACHI
