Dell Inspiron 7720 :: UEFI BIOS Does Not See Operating System
Mar 17, 2013
I have a dell 7720 laptop, which I would like the Windows 7 install on a SSD msata. I set UEFI, everything is OK, it loads the installer, run the install halfway, and it's the first reboot, the BIOS can not find the half-installed Windows, and start over again ... I have tried everything, I have the BIOS is re-installed. Windows 8 is also doing the same.
The funny part about it the same way I did two months ago and everything was fine, the machine worked, I just wanted to make Windows 7 the next and 8 easyBCD replaced with the sequence, and then he died doing it every since.
Maybe this program (easyBCD) I reached into the BIOS to do a bios update bios reset and not restore? If you do not install uefi, but then a traditional HDD for no reason, and the SSD is not uefi does not work.
I think the BIOS is going to be something, because I see the following installation to set up the UEFI, and partition, but the BIOS does not recognize (ran half the installation and over again to start because UEFI boot is not displayed you installed.) If you set it that boot device is added, it will print that you can not find a file system, but if I turn off the traditional boot then you will find the first installed unfinished Windows, you add the boot list, and then I went to the BIOS settings, restart, and again, you do not see your operating system. (none of what I just set it boot list)....

I have just purchased a Dell Inspiron 17R Special Edition 7720. It came with a preinstalled Windows 8 (so 64-bit and mandatory UEFI boot). I want to use Linux (more specifically, Archlinux) for work and Windows for games, so dual boot is needed.
I almost completed the Linux installation except for the bootloader: I need to boot Linux from UEFI and didn't manage to do it so far. Here is what I did after I received the PC:
-Disabled Secure Boot; updated BIOS to version A12
-Resized the main Windows partition and created a few partitions for Linux;
-Switched to legacy boot mode and managed to boot a MBR-bootable Arch linux installation USB drive;
-Installed most of the system switched back to UEFI boot mode, Secure Boot off.
At this time I needed to boot the kernel from UEFI for the bootloader installation program to have mandatory access to the EFI environment variables. So I created an UEFI-bootable Archlinux installation USB drive (with a FAT partition) but so far I couldn't manage to successfully boot this drive from UEFI instead of Windows 8.
I think I really tried every single combination, such as:
different USB ports; different boot entries created with F2 boot setup, with different parameters; different orders for the boot entries; hit my boot entries directly within F12 boot menu.
No matter what, in UEFI mode the system always boots the Windows partition.
Also, I could not find any relevant manual or software documentation about the A12 BIOS on the Dell site, did I miss something?
The solution that the user described in this thread to UEFI-boot to a DVD did not work for me with a USB drive.

My 8 month old "Mini 9" Inspiron 910 shows "operating system not found" on boot-up and bios shows HDD size of 0MB. Fixed shows STEC PATA 16GB-(PM).
I realize re-installing XP is my next bet but I can't boot to USB. maybe the Solid State HD DEAD?

I get the Acer explore beyond limits splash screen. It stays on that for several minutes then the screen goes black and says that Operating system not found.
I was able to get the BIOS screen by pushing F2 but didn't know what to do from there.

I replaced the HDD in my Aspire 7736Z. I ordered the disks FROM ACER. I keep getting the "No Operating System" error.
The disks that were sent by Acer will not boot and I cannot figure out how to boot them from a "bootable disk"
The BIOS sees the new HDD and the DVD player but will not boot.

My friend recently purchased Inspiron 15R 5521 with Windows 8(64Bit) OS. Can he downgrade the OS to Windows 7(64Bit)? as he has some issues with certain software, which according to the developers won't work on Windows 8. Will the warranty be void if the system is formatted and Windows 7 is installed. Is there any option to go in for a dual boot with Windows 8 and Windows 7. As per the support center, they do not recommend dual booting on a Windows 8 system.

I have Inspiron 14R N4010. Its 2 years old. Its Toshiba hard drive(320 Gb) crashed 8 months before so I bought new WD hard drive(500 Gb), which also crashed again 2 weeks before(OS drive had bad sectors apperently) . Hence i got it replaced by WD for a new 500Gb hard drive.
Now, when I am trying to install OS in my new hard drive, i am getting following error:
Intel UNDI, PXE - 2.0 (build 083)
Copyright (C) 1997-2000 Intel Corporation
For Atheros PCIE Ethernet Controller v2.0.2.3(06/18/10)
Check cable connection!
PXE-M0F : Exiting Intel PXE ROM.
Operating System not found.
after learning about possible mistakes by reading some forums
1) I checked that hard drive is installed properly, all connections are good.
2) DVD I'm using to install Window 7 is bootable one & i have used it before
3) BIOS settings are checked to boot fromCD/DVD drive. (It is not booting from network adapter which supposed to be reason for ethernet error as per many other forums)
4) I tried draining current by pressing power button for 20 sec to reset settings.(I read in some forum) but even that didn't worked.
BIOS is detecting hard drive...so that is also not issue. Could new hard drive be damaged? should i get this new one also replaced again? I need some way to confirm this before me sending it back to WD.
In one microsoft forum, I read for same problem
"update the basic input/output system (BIOS) to the latest version by contacting the motherboard or computer manufacturer and check if it works.Important: Modifying BIOS/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.
Ref : [URL] ....
Since modifying BIOS setting involves risk

I have an inspiron 1545, and recently a message that said "missing operating system" appeared when I booted it up. I tried pressing f8 and control+f11 but neither of those work. I also tried reinstalling my windows 7 but after it says "starting windows" it just goes to a black screen with a curser. I'm willing to restore it completely if its nessecary.

I've had this laptop for 2-3 years and It had a motherboard issue within the first month of getting it, I got a new motherboard and all was dandy, but now there is apparently a system timer failure. The only thing plugged in to it is my charger and the last time I used it I didn't even have internet I just watched a few shows that I had on it and then I closed it when it was running out of power. When I hit the power button it seems like its going to start, and the buttons on it light up and then it starts to beep four times then a break then repeated four times. Nothing appears on the screen.

As a routine maintenance task, I ran chkdsk /r on my Inspiron 1545 last night and it hung at 69% in stage 5 for over 10 hours. I figured it was hung for good, so shut the machine off. When I turned it back on I got the black screen with a "missing operating system". Message.
Worst case, is it as simple to get a factory restore by hitting F8 at bootup like I;ve seen posted on the web? If not, I do have the factory system recovery disks I made, but I really want to save what's on the laptop already.

I've been expecting a problem recently; when I turn off/restart my Inspiron 7720 and I press F2 to load the BIOS, I notice the bar fills but it continues and loads windows normally. I tried updating the BIOS from A10 to the newest A12. If i press F12 for boot options it works fine, it's only when I press F2 for the BIOS.

I have an Inspiron 17R SE 7720 running Windows 7 64-bit Pro which has been working fine, but I was thinking about getting an mSata flash drive to cache the hard disk, and reading on this forum discovered that my A01 bios version wasn't up to the job, so tried to update the bios tonight.
I downloaded the 7720A12.exe from the Dell site but wanted to backup my bios first. Again searching this forum, I saw a post that said there was a backup option when running the exe. Wrong.
Running it from within windows it immediately said it was going to reboot (I wasn't given an option!). My laptop powered down as if doing a restart, but immediately hung.
There was nothing but blackness on the screen, no text, no beeps. It appeared to be stuck in a boot cycle, as the screen back light was coming on, and off, and on, and off etc, for 10 minutes straight.
I powered down and powered up and I get the dell logo and can enter the bios setup, but after that, no matter what I do, I get a dos based "BOOT MENU" with just these options on:
Network Boot <- does nothing except messes up the display of this menu Setup <- loads the bios settings Diagnostics <- runs a diagnostic program which tests the hardware and reports all tests pass Change boot mode setting <- does nothing except messes up the display of this menu
I can't get passed this menu.
I've tried booting from a DVD - both a Windows 7 installation disk, and the Dell recovery DVD I created when I first got the laptop, neither DVD boots, and apart from buzzing the DVD drive, don't have any effect at all.
Both disks have been tested in another Inspiron laptop I have, and I also set the boot priority order in the bios so that DVD is the first item in the list.
I've also tried a bootable USB stick, but no joy there either. The light on the stick shows it's being accessed, but I still end up at the Boot Menu above.

Came to a point when I should completely restore the OS on my Acer Aspire 4752. Neither through Alt+F10 nor through eRecovery am I able to get around a Notice with the following "please complete operating system setup process before doing system recovery". There is only one option of this notice, that is to ok it and then the current Windows 7 Home Premium OS starts and I am not able to get out of this viscous circle. The OS works and is completely set up, so I do not understand what am I prompted to do. I see a number of postings out there, but no solution. Local Acer does not seem to know anything about the problem nor it's existence.

I have an XPS14 from the Dell outlet (UK) which means it was pre-configured. The machine has a 500gig hard disk and a 128 ssd. I was surprised to find the o/s on the large hard disk and intend to move it. Is there anything special I should take into account (dell partitions/drivers) when I do this. As I don't have windows disks I intend to clone the system disk.

I have a Dell Studio 1535 laptop that was given to me as a gift. It included Windows Vista Home Premium 32-bit...
I want to use the 64-bit version (it's an option when you initially buy the laptop), but Dell does not seem to have an option to order replacement OS recovery disks...
Is there any way I can get hold of the 64-bit Vista Home Premium recovery disks for the Dell Studio 1535, or at least somehow install the 64-bit version using my existing 32-bit product key?..

From what I have read I am under the impression that new Dell systems often are delivered with many unnecessary programs that use system resources and slow down the computer.
I will be receiving a new Latitude E6400 with Vista Ultimate in the next few days and I am unsure whether or not I should reinstall the operating system or leave it as is.

I have an XPS 14z, which has been owned for a mere 10 months. And well, yesterday I went ahead and formatted and re-installed the Windows 7 64-bit Operating System. It seemed to install fine and booted to the desktop. I then had to leave the house to run some errands, so I shut the laptop down. When I came back, I went to turn on my laptop. The Dell screen popped up, but then right after appeared a black screen reading "Operating System Missing". And well, I have been at it trying to fix this issue all day long! I have already ran the diagnostic tests, and they all were passed. So far I have tried the following to no avail:
1.) Booted Windows Disc --> reinstalled Windows = Same Problem
2.) Booted Windows Disc --> "Repair Your Computer" --> "Command Prompt" --> after "X:Sources>" typed in "bootrec /FixMBR" and "bootrec /FixBoot" = Both said successful, restarted, only to run into same problem
3.) "Command Prompt" --> after "X:Sources>" typed in "chkdsk d: /f/r" = "failed to transfer logged messages to the event log with status 50"
4.) "Command Prompt" --> after "X:Sources>" typed in "bootrec /rebuildbcd" = "Successfully scanned Windows installations. Total identified Windows installations: 0 The operation completed successfully."

Running vista 64bit. Installed software update. Now my laptop won't boot up.
I tried safe mode, start up repair tool, and ran diagnostics. It says hard ware is fine. Seems to have to do with that update.

my Vaio and so I decided to recover everything with my recovery disk.
I chose the option to wipe and erase data, and when I tried to restart my laptop... it tells me that the operating system could not be found.
I'm still under the company warranty so I was also thinking of returning it to get it fixed if I can't do it on my own.

I have always bought Dells but am leaning more towards HP and am baffled by the fact that the CSR says I cannot get a laptop with an operating system disk for use with the laptop I am purchasing. I would gladly pay a fee for the disk as I have when I have purchased my Dells.
Is there any way (other than just purchasing the operating system outside of the the HP purchase) to have HP include a oem disk with my purchase?
