Jul 11, 2011So the other day I wake up to log on to my Alienware M17x m1, which was running windows 7 ultimate x64 sp1. As it's booting up, I see the message operating system missing. So I grab my USB thumb drive (my cd/DVD drive does not work, thus I have to use windows 7 on USB). Tried to reinstall windows that way, but was getting some partition error of some sort. Now when I try to boot up with USB, I can't even get to the windows 7 installation screen. I get - The Windows Boot Configuration Data file does not contain a valid OS entry.

Jan 7, 2012I have a HP laptop that had Windows 7 installed on it, one day i got a message saying there were updates available, which included Service pack 1. So, i went ahead with the install however, when my system rebooted after the install there was an error message (i cant remember what it said, it was a while ago) so i immediately tried to put my windows 7 disk in, which would not boot. I have gone into bios and changed it so that it was the first boot item but still didn't work, even with F8, F12 etc. So i decided to borrow a recovery disk from a friend, it is a general one of the internet, i went through the repair options which didn't work, so i decided to format the hard drive which was successful. So now when you boot, as you would expect, you get a no operating system message. I try to put my Windows 7 disk back in to install it fresh but it still wont work, its like theres nothing in the cd drive.

View 0 Replies View RelatedWindows 7 Won't Boot - No Operating System Listed / System Partition Not Valid
Oct 19, 2011Suddenly my Win 7 Home Premium x64 will not boot. The system starts, POSTs then loads the DVD driver, then the screen goes black (not blank but "lit up" black if that makes sense). Then nothing. If I use Hiren's boot cd I can boot up using the "boot from HDD" option fine and Windows operates normally. System restore to a previous configuration made no difference to the original problem. I cannot boot into Safe Mode. F8 just offers me boot order options.
- Running the Windows 7 DVD I find: "No operating system is listed on the Repair Windows option."
- Running Startup Repair finds the following error: "the partition table does not have a valid system partition" which it claims to have repaired, but the error remains and Windows will still not boot.
I followed this advice:
Boot 7 dvd to system recovery options command prompt. Type: Diskpart
list vol (find the vol letter e.g C or partition number e.g. 1 for the system partition )
Sel vol C ( or sel vol 1, obviously use the correct letter or number)
act exi
My system partition was easily identified and listed as healthy so I selected it and made it active. The problem still remains exactly the same. My system is self built just over a year ago, to my knowledge has been running fine, without any hardware issues. I'm prepared to do a clean install if that's what it takes but if there is a way to fix the partition problem without that I'd like to explore it first.

Oct 11, 2012I have both Windows 7 Home premium 64 and 32 bit installed on a split partition on my hard drive, but when I try go to boot, both editions just say: Windows 7. How do I change of the operating systems to boot to for the BCD File in Windows 7 so that perhaps one of them says Windows 7 32-bit while the other says Windows 7 64-bit. I know that in XP it is just a text file you have to edit, but in 7 it seems a bit more difficult.

I think because , i had given "mark partition as active" option for one hard dive (E) in disk management when last time i opened. it did not have any data. i did not know, this will make any problem. Now i am not able to boot windows re installation dvd also. i can only take BIOS settings.

May 29, 2011I've just recently installed one of my favorite old games, Starcaft. after playing it for about a week I've found out that there is a 100 milisecond delay on any action you make when using Windows 7. I desided to hook up my old hard drive and It's telling me that it's corrupt, has a virus, I believe because the mother board doesn't recognize it I think. Is there any way that I'd be able to get that hard drive working or maybe ever use it as a second drive, some how?

Sep 15, 2011I'm been working on this problem for over a day now and now I'm stumped.I've read dozens of threads and blogs all over the internet concerning this "operating system not found" problem but none of their problems seem to be the problem that I have.My computer just got extremely laggy and froze into a BSOD (blue screen of death) before turning off and showing me the "operating system not found" message during every boot.Usually when this problem showed up, it turned out to be a hard drive failure, but when I checked my bios, it listed my hard drive as 320gb. (So I'm guessing this has nothing or little to do with my hard drive.)
Here are the things I have tried: Safe modesThe "Launch Startup Repair" (ends up with at start up background and doesn't progress any further)The "Windows Memory Diagnostic""Last Known Good configuration"I've transfered the windows 7 .iso to a bootable usb and started up the laptop it got to the Install Now window and when I press that, the window closes and it shows "setup starting" and just stays like that.The only part that seems to be working like it's supposed to is the quick start/splashtop browser option that doesn't startup anything. (It only opens a browser for internet use and no other programs).I'm guessing the next step should be to open up my laptop and see if any of the cables are loose.ut after that I don't know what else I could do.
Edit- I have just checked and now the operating system not found message doesn't show up. when I start up with regular settings, it just gets to a blue screen and restarts.
