Q: Missing Operating System/Error Loading Operating System

Hey all! I am pretty new to this kind of Win7 issues, so I hope some of you will be able to help. Story goes...

After few hours of gaming the computer died. (It happened right after switching keyboards.) Now, on every setup BIOS(?) comes up with list of options (F2 enter BIOS, F11 boot options, F6 Flash etc.). After that a black screen with error message comes up: Missing Operating System.

I tried rebooting from USB (since I have no disk-drive) and I keep on getting the answer: Error Loading Operating System.

Any ideas?


Preferred Solution: Missing Operating System/Error Loading Operating System

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

All unlikely, but possible - (a) your HDD died. (b) your bios became corrupted (c) your HDD boot sector became corrupted (d) your HDD partition is corrupted.

Does the drive spin up when you switch on (feel it)?
Check the bios to see if the HDD is reported correctly and is at the top of the boot order.
Find a bootable CD - an OS installer, or create Easeus partition manager bootable CD http://www.partition-tool.com/personal.htm and boot from it. What does the HDD look like with Easueus?

I'm trying to fix my friends Hp and I usually know what im doing. But here I have no idea what to do.

I tried going into the bios to change the boot order to cd to format and I can't. Can anyone tell me what to do.

-I changed out his hard drive with mine and it does nothing. just posts and goes to a black screen instead of trying to boot and blue screening as it usually do when you change hardrives between two computers

-Changed the Ide cables no luck.

Hi all,

Installed a DVDRW drive but comp crashed when installing some software and it stopped detecting my Primary Master and Slave drives. I've fiddled about with the Master and Slave configs and have managed to get it to detect my HD and DVDROM.

I've unplugged my DVDRW and my small HDD and am trying to get windows to load up.

After using FDISK /MBR an rebooting, I get "Missing Operating System".

Tried installing Windows XP after formatting, it seems to have installed but it's not loading.

Current config:

Slave: Pioneer DVDROM (not the DVDRW)
Master: Seagate 80GB (C: = 15GB) & (D: = 61GB).

D: has files on there that I'd like to recover. Too big to put on floppy.

I've run a search for similar problems and tried some of the solutions but no good. Any ideas? Thanks

then it says hit ctrl+alt+ delete to restart. and the thing is there is no operating system on it. and it says this whether or not a cd is in the cd/dvd drive. i have tried windows 7, and even my old windows xp disk and nothing. it isnt the same thing where you can repair it through the disk it doesnt give me that option just goes straight to that. and it restarts and does it all over again. I first tried to install through USB mode, that didnt work so i quick formatted the hdd on another computer, the hdd is a wdc 750 gb. the motherboard is a gigabyte m68mt-s2. now that i got a piece to make my old pata disk drive to a sata i could do disk. i have tried pulling the motherboard's battery out and putting it back in but nothing. any help would be much appreciated.

I have a problem with my laptop. it's a ideapad z470.
my problem is that whenever I turn on the laptop, it gives me a error loading operating system message.
I have searches multiple threads and tried them but it didn't work for me.

What I Have Tried
1. windows repair disc- after it loads the Microsoft loading bar, the screen stays black
2. windows installation disc- screen turns black but with movable cursor.
3. pressing f8- after loading all the files, it just stays there for a few minutes and then black screen with cursor.
4. re-putting back in the harddrive- no effect
5. system recovery button- stays on "loading files" bar for a while then to black screen

The BIOS detects the harddrive though.

I know you all are quite good at helping others fix their problems, and I have been stalking these forums for quite some time. However, I have recently gotten an issue with my computer booting that I can not fix, or find a fix on here.

So, about two hours ago (On this current PC I am typing on now.), my computer decided it would basically freak out. I got a few three pop ups, saying sticky notes has crashed, gave me the option to select cancel. I got one pop up for each sticky note that I had up at that time.

Then curse had done the same thing, which I found was odd, as curse has NEVER once crashed on me.

Then suddenly, the dreaded BSOD appeared, and before I could even try to restart my computer, it shut it self off.

I went to start up my computer, thinking maybe it had just crashed. It did its normal start up stuff, got to the welcome screen, and took about 5 minutes to load past that. Once it did, another 5 minute load or so on a blank, black screen. I walked away as it was taking a while. I came back, and on the top of the screen, it said "Error Loading operating system."

I had no errors, or any other warnings before the system crash, nor did I have any viruses (Checked three days ago.)

My operating system is Windows 7, I use an Intel R Graphics card, and my computer is a HP touchsmart 520 PC, all in one, antivirus is the AVG free edition, and I use MalwareBytes, both are run on a regular basis.

Reboot into BIOS setup to see if the HD is detected. If so start with the HD tests and then work through the other Troubleshooting Steps for Windows 7.

You'll note we recommend an AV which is not AVG, which hasn't been recommended anywhere for years since it bloated up and never slimmed back down. We only see problems with it here. I'd uninstall it and install MSE asap.

So the HD and AVG look like your likeliest suspects, however if you still have the HP factory preinstalled Win7 then that is the worst install of Win7 one can have, so it could be a combination of these or something altogether different which will likely turn up as you work through the steps.

Now would be a good time to consider getting that one great Clean Reinstall - Factory OEM Windows 7 since you only need to get it right once, then save a backup image in case you ever need to reinstall again it would be a 20 minute reimaging operation.

Hi there. I've searched the web and these forums for information about this error message, and found quite a few suggested solutions; however, this error seems mostly to occur after a fresh install of Windows. This is not the case for me.

Over the past month, I have noticed my computer running slower, and crashing more often. It became particularly severe during the past week. I would get programs simply freezing on screen for a minute before I could move the cursor again, or simply freezing so long the only option was to restart the computer.

Two days ago, I woke up to this black screen with the message "Error Loading Operating System". The only change I have made to the system recently is, two weeks ago I got a blue screen crash and after reporting the issue was taken to a website which said the crash was due to a chipset driver of some kind and that I should update it, which I did as per the instructions that were given. However I had the slowdown and crashing prior to this so I'm am not sure if it is related in any way.

Any information or suggestions anyone could give is very much appreciated, and I thank you for taking your time to read this post.

!!!!!THANK GOD!!!!! I just had this same problem and was reading this forum to try and find an answer (though sadly i did not). Instead i decided to boot from my original windows install disk and run the recovery console (press R). at this screen type 'FIXBOOT', it will prompt you for a confirmation so just say yes (type 'y'). It will write over your previous boot files BUT NOT YOUR PERSONAL DATA!!!!! after this runs and says that it has completed successfully, type 'exit' and the console should quit and your computer is back.edit: caution, i think this is only a temporary fix (meaning you'll have to go through the same procedure every time you boot your computer) so i would recommend backing up all of your files onto an external hd and then reformatting your computer (by the way i have the same computer, Dell Inspiron 5100, so this fix will probably work the same for you as well).Was having the same problem. Followed the instructions, but computer still won't boot. Now, its not even giving me the option to boot from CD. The new message Reads "Windows XP could not start because the following file is missing or corrupt:\WINDOWS\SYSTEM32\CONFIG\SYSTEM" At this point, I just want to do a clean reinstall of XP. There is no data of importance on the computer. Any help would be greatly appreciated.

I have a computer that a while back I got the blue screen OD and was trying to fix it myself. I don' t know what I did but after a day of working on it, it went to a black screen that says error loading operating system. I know it was dumb to try to work on it myself without professional assistance but I did. I have been searching the internet for a fix but cannot find one and would appreciate if somebody can help.

I am sure your first questions will be, what happened to get the blue screeen, what code did it show and what did you do that caused the error loading screen. This happened literally the week before we were set to move and I ended up just leaving this computer in storage until I had time to work on it. That was a year ago. So I don't remember how it happened, what the code was, or what I did to get the error loading screen. Sorry.

I am deeply appreciative of any help you can lend me.

I was thinking really hard trying to figure out how this happened and now I remember, My cousins xbox harddrive was not working and I was trying to figure out how to back it up so he didn't lose everything on it. Unfortunately when I hooked it up as a slave drive it wasn't reading even though I could feel the disk turning inside. So, in the process of disconnecting wires trying to figure out how to make it work, my computer started having problems. Not sure what I did but I thought maybe it was a bios issue?

I am using windows 7 on my computer and recently I figured that my computer started freezing a lot so I decided to install a fresh copy of windows. I did the same and scanned my whole computer and found no viruses either, the freezing problem was still not fixed. I searched up some but found no good solution. Then somehow the condition started getting worse, my computer stopped booting and it started restarting itself at the win7 startup animation. And then even worse.. now it only shows a black screen after turning it on and then shows the error "error loading operating system"after a few minutes. I tried many things I found online but nothing worked since I can't even get Into my windows for now. Safe mode isn't working either, I have no idea what to do now, please help me with this error. Or could it be a hardware problem too?
Please remember I only have a bootable windows 7 USB with me, no cd/dvd at this moment if the fix requires a copy of windows.

A:Error loading operating system

ok, the fact that a clean install didn't fix it pretty much confirms that it is a hardware issue, have you tried startup repair yet? hat might reveal what is stopping you getting into the PC and at least allow you to get in and find out what is wrong.

There is a problem with my old PC (Windows 7 x32, Intel duo core processor, 2.5 GB RAM) which was custom or assembled, it says 'Error loading operating system' and I have been trying to fix it for hours..
Earlier when this happened (A lot of times), I fixed it from the Repair option when I press F8 contineously, but when i keep on pressing it, nothing happens (System Repair Blackscreen does not come).
It happened when I pressed the restart button in my CPU when my PC was stuck for a long time, instead of waiting and manually restarting.
The biggest problem is that I LOST my Windows 7 CD. All I have now is just a USB with backup files.
When I put on the USB while booting, it says 'BOOTMGR is missing, Press Ctrl+Alt+Del to restart' but it shows the same thing when I restart.
When I pressed F10, It showed the Boot Option Menu, it had 3 options:
• SATA: Optiarc DVD RW AD-72203
• Realtek Boot Agent
• MBIC SS MMoser Baee Disk PMAP (That one is my USB)
These 3 didn't work either....
So, Please help me to find a way to fix it.
Ask me if you want any more information.

Ok I have been working on this a few days now with no luck. I was running a normal windows scan disk. After it finished the computer restarted and when it came up it said that it had a disk read error. After formatting the hard drive and reflashing the bios it started to say error loading operating system. I have tried fixboot and fixmbr. Formatted the hard drive with a quick, full, and low level. Ran the Maxtor Powermax utility that says my drive is fine. I have tried using another drive. Still all I get is error loading operating system.
I am about to try to totally wipe the MBR but that is the last thing I could think of unless it is a motherboard hardware problem. It has been working now for months without any problems. Also going to try Windows 2000 to see if that makes a difference.

*edit I don't know if this will help but the error happens after xp copies the files to instal and restarts. It never gets to the second part of the install.

Can you boot into Safe Mode. Press F8 immediately after you start the computer begin pressing F8. This will take you to a page that looks very similar to the picture below. This is the Advance Boot Options. You need to use the up and down arrow keys to navigate on this page. Once you have moved the cursor to the option you want press Enter on your keyborad.

hi.. i've seen error loading operating system in my system. i've formatted the hard disk and installed xp os in it by keeping the hard disk in another system(second system's hard disk is replaced with the issue hard disk). now when i try to keep the issue hard disk in the original system and try to boot, it is showing "error loading operating system". i've tried changing the bios settings to default but same again. what is to be done now? how can i clear cmos memory? will that be helpful? how can i change to large or lba of access mode? i don't get that "access mode" in the bios setup.. help me getting the issue resolved...

A:error loading operating system

Hi Isaac. You can clear the CMOS memory by removing the battery (looks like a quarter) on the motherboard for a minute or two and then re-install it. Just pay attention to the polarity. Wiill it help? Hard to say. Will it hurt? Highly doubtful. You'll just have to set the information back up that you lost when you pulled the battery. Nothing major.

Does it give you any other error information or just that it has an error loading the OS? It almost sounds like your system is looking at an address location to start the OS but the address location isn't where your OS is.

If you use your laptop recovery CD's you will lose the lot in most cases as it reinstalls Windows and leaves the laptop as it left the factory. But you don't have them?

If you tried to use your Dell CD it will fail as the Dell CD will have all the Dell specific device drivers, and will likely be BIOS code locked to the Dell, so it will either refuse to even install (likely) or if it did install the laptop would be borked as all device drivers would have the wrong code force fed and fail. All data would also be lost.

About now you should be considering dropping the HDD out of the laptop and attaching to an XP desktop via an adapter (2.5 to 3.5 IDE) or in an external USB case, to recover your data.

Data that only exists only on a HDD is data that you don't care about losing, as file systems or hard drives can corrupt or fail at any time with no warning. And they do.

You may have to get your Sony CD's or buy another copy of XP.

My computer been acting weird since about 4 days ago
everytime it load it keep saying "Error loading operating system" on the start up screen instead of showing the Window Xp logo.
why is it saying that?
how can i fix this?

A:Error loading operating system!

This is a tricky one - I had this problem with a computer in my house a while back, and had to reinstall. Firstly, you're going to need an XP install disk - if you got one with your computer, that should be fine (you don't need it yet, but just in case the following doesn't work). Also, your comp's specs and info would be very helpful.

1. Try to boot into Safe Mode - when the computer boots, as soon as you see your manufacturer's logo, press F8 or F12 (it depends on what make you have). Then, from that menu, hit 'boot into Safe Mode', or the text to that effect.

2. If safe mode fails, try booting into safe mode with command prompt - another option on that menu. It may hang at a certain DLL which could indicate a problem with that file. After you do those two things, we'll proceed.

I'm looking for solution for my friend's laptop using WinXP SP2. She keeps getting the "error loading operating system" when WinXP starts.
Does she need to format the whole harddisk to get things work again? is there any better solution as she does not want to lose anything on her harddisk if possible.

A:Error loading operating system

I guess you could just boot from the win xp cd and say 'repair previous installation', or if that doesn't work, just re-install windows (by booting from the cd again). Data on other partitions will not be lost - only you might need to format the partition you're installing xp in if you decide to do a reinstall.

I'd be grateful for anyone's thoughts on this one.

I downloaded the latest security patch from MS [the one about remote takeover of computers] installed it, restarted and then got a horrible error message - error loading operating system. Its like an old fashioned command prompt that you see in the movies - just that single line on a completely blank screen with a flashing cursor awaiting instruction.

I'm running a dell 8200, with windows XP home, service pack 2 and all other patches etc. installed. Everything was fine prior to this. What happens is that I switch on, the graphics card details flash on the screen [as normal] followed by the Dell splash screen with F2 and F12 prompts and bios version [a08] then the above blank screen. Nothing works once the above screen is reached.

From reading the web I've kind of figured out that this is a problem on the bios and that, somehow, my bios has become corrupted. One solution offered on a few sites seems to be go into bios and then change the hard drive access mode from auto to large, but i'm not sure about this and it sounds a bit scary.

Any thoughts?

My prime concern is that I have a lot of data on my hard drive [stupidly only partly backed up - I know!!!] and I'm really worried about losing it.

I should confess that I'm a bit of a newie at these things and my technical knowledge is very limited so please, phrase any replies in simple terms.

My prime concern is that I have a lot of data on my hard drive [stupidly only partly backed up - I know!!!] and I'm really worried about losing it.Rightly so, but who among us have not been caught in this situation?Without addressing your original issue, I just want to speak to getting the data off of the hard drive. You could always remove the hard drive and install it in another computer as a 'slave' drive. The working computer should still boot up from the 'good' Master hard drive, and then you will be able to navigate (start > my computer) to the slave drive and recover your data. More info on how to install a second drive can be found HERE.But of course, if you need help with this or any other procedure you can just ask for help here and we can explain it in more detail or refer to somewhere on the web where it will be explained more fully.

Hi everyone!

Well as the title says, I got that message when booting. Actually it is a long story before i got that message so i'll try to sum it up. So, what i've done and what happened are as follows:

27 October 2012: I built my PC from a scratch.

three weeks ago: I began suspecting HDD failure because it is not detected in the bios frequently, failed short dst and long generic test in seatools for windows and began to make weird sounds (kind of a scratching or grinding noise, but I can't really describe it) only when booting or extracting .rar files.

two weeks ago : the problem with the bios was gone. But the sound retains.

1.5 - 1 week ago : the PC loads gadgets and some programs (that launch on startup ex. drivers, antivirus) a bit slower. I suspect the HDD is causing this because the other components are fine and my PC could play games in full HD. Windows explorer also crashes sometimes, and minecraft too.

Just YESTERDAY : I've had enough with constant explorer crashing and slow system, so I decided to open my HDD to check for hardware problems (It's a stupid move, i know) but I failed because after i opened the screw and tried to open the cover I can't because the cover is shut tight and prying it open wont work. Then i just put the HDD back together with the PC and booted, then magically an error status 0xc000000f appeared on my screen. I searched forums and run repairs from my installation disk but my OS is not listed. So i went on to the commant prompt and use... Read more

I have a Sony Vaio VGN-N130G, Model PCG-7T1L.
Attempted a system recovery, but while on step 2 of 4, it froze at 12%, then flashed an error 400 message. Computer restarted and now it's a black screen with error loading operating system.
Tried resetting the BIOS to default, but still doesn't work.

I do not have a recovery disk, was told it's all built in. I do have a Vista upgrade CD that I have not installed. Not sure if I can restore from there. I have no problem starting over from factory settings, nothing on the computer that I have to save.

Thanks for your help!!


A:Error loading operating system

Hi .If XP is the operating system installed...you cannot use a Vista CD/DVD to do anything other than remove the XP install and then install Vista anew.The only Error 400 message I am familiar with...has to do with Internet connectivity. Can you post the exact error message?http://www.docs.sony.com/release/VGNN100series.pdfPage 108 of the above link starts listing the steps users with problems should take. I can't suggest anything beyond that because Sony modifies the way that their systems boot, etc.Louis

I have an LG PC. I have office Professional 2007. The hard drive is seagate 320 Gbytes. It was operating perfectly, until I moved it to another room. I turned it on and the screen said analog power saving mode.
I have changed the battery on the motherboard, double checked all connections, and reboted it and now the screen says Error loading operating system. If I press del it takes me to CMOS utility. But I don't know what to do. Can anyone advise what I should do. Step by step would be great.

A:Error Loading Operating System

Hi megatron, and "Welcome to the Seven Forums." . . .

Now to the problem at hand. First we need to know what operating system you are using. Microsoft Office 2007 is not an operating system. To find out what OS you are using "press and hold the down the Windows Key then push the Pause Key." Doing this will bring up what is known at the "View basic information about your computer."

From that screen you will see the basic information about your operating system and the computer itself. Now type in that information so that we who wish to help can see what operating system, and computer you are using. With this information we can at least start to give you some ideas as to the problem. . .

My computer did a crash dump and when it restarted there was just a black screen saying error loading operating system, what do I do. I have an old asus laptop with Windows Vista.

Hi all, I have searched several tech forums for answers, found some, but none have fixed my issue.

When I start my computer, I get the black screen with one line across the top saying, "error loading operating system".

I thought by putting the Windows disk in, I could run a recovery. The only option it will allow me to select is to reformat the harddrive. I would like to figure out why I get this message and how to fix it.

If it can't be fixed...I have also tried to make this harddrive a slave to another one. I am able to see the new drive in my computer, but if you click on that drive, it says drive is not formatted. Is there any way I can get the data off of this disk?

A:error loading operating system

ok...so you put in your Windows recovery disks in..and then what did you do? What version of windows to do have? XP? (if so is SP2 installed?) What did you do last before you got this error message? Thanks

Hey guys,...not sure if this is under the right forum but I'll post it here for now. Mods, if in the wrong forum, please relocate as you see fit.

Recently, I've been getting this msg "Error Loading Operating System" whenever I boot up my computer. I tried running a diagnostics, and the hard drive was detected and also passed. Do you guys any suggestions on how to fix this problem? Thank you in advance,

A:Error Loading Operating System

I think you were on the right track by testing the Hard Drive. You should immediately backup important data, and then try another diagnositic for confirmation.Go to the manufacturer's website and download their disk utility to check the hard drive out (this list is kind of old, some of the links may have changed): Fujitsu "FJDT" DOWNLOAD Works with fujitsu models only.
Hitachi / IBM - DFT "Drive Fitness Test" DOWNLOAD Works with all manufacturers.
Maxtor "Powermax" DOWNLOAD Works with all manufacturers.
Samsung "hutil" DOWNLOAD Compatability unknown.
Seagate "Seatools" DOWNLOAD Works with Seagate drives only.
Toshiba - N/A There are no tools available for Toshiba, but you may be able to use IBM or Maxtor's.
Western Digital "Data Lifeguard" DOWNLOAD Works with WD drives only.

Hi everyone. I really don't have a clue about what has happened to my pc. I shut it down fine last night - no problems. I haven't installed anything new either. This morning i turn it on again only to see a black screen with: ERROR LOADING OPERATING SYSTEM.

I tried putting the pc into safe mode but no luck. I tried F1-12, DEL,ESC etc on boot up but it just refuses to go into safe mode. The error message remains and doesn't budge. All i hear is a beeping everytime i'm pressing one of the buttons mentioned above. I honestly don't have a clue where to start with this. I'm really worried about losing my files as i only have half of them backed up and they are really important. Is there any way i can fix this problem and retain my files at the same time? Any help would be appreciated. Thank you

EDIT: here is a pic i took of the problem:


A:Error Loading Operating System! HELP!

The line just out of sight in the screen shot would be the Pri. Master drive. Is there a drive listed there? It looks like it's trying to boot from CD, possibly because there is no hard drive found. There is a distinct possibility that your hard drive has gone south.

My computer appears to be running perfectly normal apart from the fact
that whenever I try to restore a partition, clone a drive or attempt
do a clean install, it will not boot and I get the message saying, error
loading operating system. It can't be the hard drives because it
happens even with my brand new hard drive. If the drive I'm using
boots perfectly and I clone it to another drive, surely they are both
exactly the same. So why will the newly cloned drive not boot?

A:Error Loading Operating System

Because the new drive isn't exactly the same as the old one (even "identical" drives aren't the same).
But, I don't think that this relates directly to your problem (since a clean install wouldn't suffer from this issue).

Could you describe what you're trying to do in a bit more detail so we can start troubleshooting it at the appropriate level?

A:Error loading operating system !HELP!

are you booting from the cd/dvd drive you might wana try to format it then try and install your 2000. if your computer will not boot then put your windows xp disk in your drive then boot using that as your primary boot device then use repair utility on your xp disk then use bootcfg. this should restore your boot driver. i think the bootcfg command line is bootcfg /rebuild but i cant remember that well as it has been a while since i used it

Hello elimelim and welcome to TSF!

Have you tried unplugging your SATA/EIDE cable from your harddrive or maybe changing the cable? If this doesn't work, do you have another computer and plug in the harddrive and see if will detect it? If not, time for you to upgrade then.

A:error loading operating system

Hello and Welcome to TSF,

Enter bios: press F2 when pc first turns on
Boot order:
cd/drive rom
other devices (varies)

First lets test the harddrive.

Go here for a HD utility:
use seagate tools if yours is not listed, otherwise you can use these below:

dban - http://www.dban.org/download
killdisk - http://www.killdisk.com/downloadfree.htm

Burn the image to a cd:

perform a harddrive test, if harddrive test passes then
perform a full erase of harddrive.

if everything goes smoothly, proceed onto installing xp windows

After windows is installed, install drivers next.

Go here for the drivers for the pc:

Note: install the chipset first before any other drivers, reboot pc after each
driver install.

install protection - antivirus and antispyware protection for the pc.
Update windows using the window update icon under start button, all programs

I was attempting to load XP on a separate drive from my Vista machine. Booted in the XP CD, formatted and began the installation. After the setup files were copied to the other drive, the computer rebooted to finish the installation. Upon reboot, I got "Error loading operating system".

Reading further, I see that the mbr, boot sector and boot files were overwritten on my computer. I booted from my Vista DVD, navigated to the Boot directory, and issued "Bootsect.exe /NT60 All" at command prompt. Says it was successful. I reboot and still get the same error.

I also tried the automatic repair option. It didn't find any problems and didn't fix the error.

Booted again to command prompt from the Vista DVD. This time tried:
bootrec /FixMbr
bootrec /FixBoot
bootrec /RebuildBcd

When I issued last command, it said it was successful but # Windows installations found was 0.

Also did a chkdsk on my hard drive and came back clean. All files and directories are still present as well.

Rebooted and still getting the same error. What do I need to do?

Hi I have been trying all day to dual boot using the tutorial and no success.
I have windows 7 install on my computer. I want to have windows xp.
Now I have shrink my hard drive so I have 2 partitions now. Ok the problem is When I boot xp I goto install on D:/ the new partition it then copies all the files to that hard drive all good so then it wants to restart which is normal.
Then When it reboots it will say error loading operating system or just nothing.
Then I cant even Run windows 7 I have to delete that partition on windows xp and then put windows 7 and repair startup and Im back on again. It has to do something with the boot loader or something because I reckon Its trying to do start windows 7 but there is xp trying to install it self. Im not sure but I think I have tried every idea.
I have tried 2 different cds of xp.
