HP Laptop No Operation System Found Boots Only With Installation Disc
Jun 28, 2011
I have a HP dv9920us. A month ago I upgraded to win7 from vista. Everything was working fine until a couple of days ago when returning from work I found a black screen and an error message " no operating system found". No attention paid since I thought that my hdd went bad. So got a new one installed it but got the same message. So went into BIOS and saw that no hdd was detected. My laptop has 2 sata ports so I changed port and to my relive BIOS recognized my hdd in this 2nd port leading me to believe that the first port had gone bad. I did a clean win7 install. Everything went fine. Installed drivers etc no problem. During the first boot after and right after the post message the laptop just suddenly shut down and rebooted and then shut down again just after the post message. This loop went on for a couple of times and finally ended to a black screen with the message " no operating system found". Checked the BIOS again and the hdd was there. Booted the machine with the installation dvd in the drive this time and after the same loop for a couple of times (boot-post message- shut down- reboot ) instead of going to the no "operating system found" it continued and loaded win7. I've performed every possible test that I know for checking memory, hdd etc and everything looks good. The bottom line is that now the only way that I can use my laptop is to boot it with the installation disc in and it loads and works perfectly. If I try to boot it without the disc I end up with the "no operating system found".

At the startup of my computer. I get a black screen with white text saying "Operation System Not Found" it is "OPERATION" and not "OPERATING". I first found this problem after a windows update. Its not an issue getting into my computer since all I have to do is hit the enter button on the keyboard and the laptop acts like nothing happened. Whats going on? Its a little annoying getting this message, and it some what scares me that something will happen to my computer. I feel like the startup is a bit slower, but nothing major.

Firstly I should say that I am primarily a mac user, and it is not my laptop I am posting about. Although I am reasonably knowledgable about Windows, I haven't used it since XP, about four years ago, and so am pretty rusty.Basically, my girlfriends computer randomly turned off about a week ago, she assumed it was a dead battery, plugged it in, and then when it turned back on it wouldn't boot displaying error message: missing operating system.As it is a Dell laptop it didn't come with any installation discs, and I totally forgot to even make a repair disc when we got the laptop. I managed to get hold of a Windows 7 Installation Disc and license key for Windows 7 Ultimate 64 bit through my university. I think the laptop was previously running Windows 7 Home Premium, but that's all I know, and I'm not entirely sure of that fact.
Anyway, burnt the .iso to disc and have tried to boot several times from DVD Drive. The laptop loads the files from the DVD fine, and gets as far as the "Starting Windows" screen, where it seems to get stuck for a few minutes, until it becomes a black screen with just a cursor (the cursor still moves). This also happens with an 64 bit repair DVD I also managed to get hold of.

Is there any way to use a windows 7 Ultimate Upgrade disc as a installation disc? Or would I have to go out and get another Windows installation disc and then use the upgrade disc?

My boot menu originally consists of Vista (C:) and recovery partition (D:). To install Windows 7, I shrank C and made a separate partition (W:)
Now I have 3 partitions: Vista (C:), New Simple Volume (W:), Recovery (D:).
I installed Windows 7 to the (W:), and it reboots a few times during installation. My situation goes as follows:
Initial installation---Reboot (1 of 3)---bypasses the boot menu and continues installation---Reboot (2 of 3)---boot menu shows up and I can choose to continue the installation of Windows 7, or go to Vista. When I choose Windows 7, it finishes installation---Reboot (3 of 3)---No boot menu is shown. Computer boots into recovery partition.
Why is this happening? Repairing Windows 7 or Vista using recovery partition doesn't help either. It basically just forms a loop by booting to the recovery every time.
Interestingly, the only way I can start Vista again is by reinstalling Windows 7 and wait until the boot menu screen show up after the reboot (2 of 3).

I want to make a 100% automated Windows 7 installation. (Literally 100%, meaning you do not have to know anything to install it) You only need to put the DVD into the DVD Rom and restart the computer and it will automatically:
1- Boots the computer from the DVD (No need to set the DVD Rom to the first priority)
2- Formats the drive C:
3- Installs the windows and drivers and some software
I know how to do part 3, but I'm not sure about parts 1 and 2.

I have a Z77 mobo with a new SDD and a HDD from the old PC. At first I installed Windows 7 to the SDD and I could only boot into it when I disconnected the HDD. When I started PC, the logo was shown for a second or so, and then it went into repair mode, the "preparing installation files" progress bar ran twice and the system booted into GRUB that was left on the HDD. I've tinkered in BIOS a lot trying to fix this, but to no avail.Now I've decided to also install Linux (OpenSUSE 12.2) to the SDD, and hoped that GRUB2 would solve my problems. Nope, it didn't detect my Windows 7 at all! (however, it did detect the two(?) old Windows 7 mount points from the HDD). I couldn't even get to boot it by forcing "Windows Boot Manager" from BIOS. I tried to fix this with DVD repair, at first I couldn't get it to work by launching the DVD in UEFI mode, the other one worked, but it only messed up my GRUB2 and I couldn't boot to either system. After some unsuccesful tinkering with bootrec, I found this thread and followed what OP and the best answer guy did, which sums up roughly to this:
Code: C:> bootsect /nt60 C: /force
C:> diskpart
DISKPART> select disk 1
DISKPART> select partition 3
DISKPART> active
DISKPART> extend filesystem
DISKPART> exit
C:> bootrec /rebuildbcd
Then, Windows Repair detected my installation and said it fixed the problem. Now I still can't boot into my system normally (again, it reboots after "Windows is loading files"), however, I can get it to boot after the timeout ("Press any key to boot from DVD") from Windows 7 installation disk! I have no idea what's going on.Here is a screenshot from diskmgmt: The strange thing is the 128MB partition - I suppose this could have been MSR partition, while gparted shows it's a Linux partition! Is this possible, that OpenSUSE installer messed it up?
Also: Code: C:Windowssystem32>bcdedit /v
Windows Boot Manager

I wanted to make a new partition on my hp laptop on the only disc it as.Unfortunately,because it came with already 4 partitions I accidentally turned the disk into a dynamic disk.Now its booting normally but I cant load the system Image that I have created before the partition.Other than that the pc is running smoothly.As I said this is the only disk on the system.Is it possible to convert the disk back to basic?After a lot of googling I found some exmples but all of them assumed you had a second disk on your system.Is it possible to convert the disk back to basic without having to reinstall windows?(I have no windows cd

Ok, so earlier today i decided that i needed to restore my laptop to factory default. As you can see from the title, i use an acer laptop which means i used the acer Erecovery software. All went well at first, although it took a stangely long time at a screen which said "setup is starting." The problem now is, I am now stuck on the acer 'software installation screen!' It is stuck at 41/48 where it is trying to install clear.fi v1.0. I think i heard the sound of an error earlier which worries me as i dont want to force restart my laptop as it clearly says not to do that and doing this caused my hard-drive to break last time

I tried a registry tweak to fix my home networking issues and came up with a major fail. Long story short, I changed the rpcedptmapper value and the system won't boot.I put the HDD in a cradle and it won't get recognized. HP in all their wisdom, sets the recovery disk to obliterate the entire HDD even if you created a separate boot partition

So lately my computer's firewall has decided to not work so I searched around and eventually concluded on doing a upgrade reinstall. As I didn't want to lose any of my files, drivers or programs. All seemed like it went well until the computer rebooted for the last time before it reaches the " Setting up for first use " dialog Though before this was able to happen the computer went into a reboot loop with bsod 0x0000001E
After a large amount of reluctant clicking The computer NOW only boots to the System Recovery Options window and the ONLY option is Startup Repair ; There is NO command prompt no diagnostics, nothing, Just Startup Repair, in which start up repair is unable to do anything and continues to loop itself with a Don't send dialog
I have tried inserting the installation disk and accessing the Repair Computer but it presents an incompatibility error.
I have no F8 menu at all, (no safe mode, which I can't access anyway because the computer can't set up for first use).

I am getting this <<This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer Package>> Yesterday I clean uninstalled my photo editing programs, Photplus X4 and PanoramaPlus, which are similar to Adobe Elements. The reason was that certain pics would not display, although displayed elsewhere.This morning my attempts to reinstall from the manufacturer's DVD Rom were unsuccessful with the above error.

I am still quite puzzled as to how are you supposed to install the Windows 7 OS without an actual CD? I've only done it previously with XP home edition and I had a CD. If you still do not understand what I mean, I'm confused on how will the OS, during installation, gather the information when there's no CD inside to read from?
My second question would be, which one of the versions (Home, Professional, Ultimate) is the best for GAMING? I have no need for security, but anything that would make my games, internet, etc run smoother would be of use.

When I start up my laptop (HP Pavillion dv5-1125nr, Windows 7 Ultimate ~3 years old) it loads normally... Until it hits the login screen. The , it starts to go, makes the sound... Then goes black.I just had my monitor and motherboard replaced for another issue I was having, so I don't think it's a physical issue. I have also ran a few malware/spyware tests and nothing comes up. My diagonstics, as well, turn up cleanly.The laptop runs perfectly in safe mode, however

I bought a W7 Home Premium, the discounted version for students, and I'm trying to install it on my Acer 6930G (500GB, ram 4GB, ...right stuff for W7).
I'm actually running W Vista x86, and I know that in order to run W7 x64 (the one I bought) I must do a custom installation from the boot. And I'm doing so, well trying to...
After the window asking for my location and keyboard input, I continue but then I get stuck.
A new window pops up asking me for a device driver...it stated "device driver not found"...
I read a lot on the internet, but that's driving me mad...
how can I solve the problem and having that OS running?!
I'm going to sue Microsoft if that OS is not gonna run... xD
