Windows 7 not booting

Ok so i had a dualboot setup with windows 7 and ubuntu.
I decided to remove the ubuntu partition to install windows 8 instead.
I used Easybcd to change the bootloader from grub to windows 7 bootloader, and i then deleted the ubuntu partition. I also deleted my windows 7 recovery partition to gain some more space (which i now regret). I then needed to combine the unallocated spaces, so i used easeus partition master to move my C: drive all the way to the left, and have the 2 unallocated spaces beside each other so that they could be merged. When i applied the changes and the computer rebooted, i was presented with an error that said:

PXE-E61 : media test failure check cable
PXE-M0F : Exiting PXE ROM
Insert bootable media and press any key to continue

It also said something to do with my network card, which im guessing means that it has not found any bootable os on my hdd so it is booting from network as a last resort.

Please help! I would like to now if it will be possible the get my os running again, or if i will have to reinstall windows, or even if my hdd is so destroyed to the point that i cant install an os.

Thanks, any help is greatly appreciated

Unplug all other HD's and peripherals. Make sure Win7 HD remains set first to boot in BIOS setup, and that the HD itself is detected under Storage devices there. If not replace the cable, and if necessary the HD.

Boot into Windows 7 DVD System Recovery Options or Windows 7 System Repair Disk to Mark Win7 or it's 100mb System Reserved Partition (preferred if you have it) Active.

Then run Startup Repair - Run up to 3 Separate Times until Windows 7 starts and it's boot partition holds the System Active flags.

If this fails when System Reserved partition is marked Active, move the Active flag to Win7 partition itself and then try the 3 repairs again.

Be aware that sometimes GRUB can corrupt Windows 7 beyond repair when on the same HD. If problems persist I would delete it completely and then for any future Linux Dual Boots use separate HD's booted only via BIOS, or Dual Boot - Windows 7 and Linux - Windows 7 Forums.

If all else fails it may be necessary to wipe the boot sector of interfering code using Diskpart Clean Command before Clean Reinstall - Factory OEM Windows 7 which steps are same for retail.

Ok thanks, I tried some of the mbr fixing commands but nothing is working. I think I'm just going to do a clean install of windows 7. It doesn't really matter too much because I was able to get my data off the drive with a Ubuntu livecd. Anyways when I reinstall which command should I use- the clean or clean all?
Also instead of doing this command in cmd prompt, could I just press the delete button during the windows 7 install when it asks you which partition to install on?

What MBR commands? I gave you specific steps which resolve this in 90% of cases none of which involve running XP-era commands that are now all automated in Win7 Startup Repair which tests and fixes a dozen other parameters at the same time.

Use Diskpart Clean Command

The closer you follow these steps to Clean Reinstall - Factory OEM Windows 7, the more of a perfect install you'll get and keep by sticking with the tools and methods given.

Thanks I did the diskpart clean command and successfully installed windows 7. I only have one issue-before all this trouble started I had a dell recovery partition which I erased to get some more space.(it was around 15gb from what I remember) I no longer see this partition in my computer or disk management.

I don't really want to do anything major to get it back since its pretty small, but if anyone knows if its a simple fix please let me know.

Anyways thanks for all the help. From now on,if I want to play around with operating systems, I guess I'll just stick to a virtual machine. Lol

Had you read Clean Reinstall - Factory OEM Windows 7 it anticipates the Dell Recovery and Diagnostics Tools partitions in a Special Note for Dell Owners at end so you would know all of your options and best choices.

To repeat, Recovery partition will not run on Dell Systems that relied on F8 System Recovery Options to trigger Dell Windows 7 PC Restore.

You were also to test the Diagnostics to see if it runs to decide whether to save its partition.

You should rely on a Win7 backup image of your fresh install for recovery or reinstall going forward. Backup Complete Computer - Create an Image Backup

I dont need to make a system image backup, I already have a windows 7 disc. I read what it said for dell users on the guide, but that doesn't really apply to me. I had already wiped that partition before my computer got all messed up, so the dell recovery options don't exist. What I'm asking is where did I that partition go? It no longer shows up in My Computer or Disk Management.

That's also why it says in Clean Reinstall - Factory OEM Windows 7 to make your Recovery disks first in case you ever need to restore to factory condition. This is so rare I've never heard of anyone needing it, but might be needed if Dell wants their factory preinstall on there to ship it back under warranty, or you wanted to sell it just like it came from factory.

But why would you need that for yourself now that you have a Clean Reinstall which is vastly superior install? Once it's set up according to the tutorial, save a Win7 backup image to use in place of Recovery or reinstall.
