Windows 7: Windows 7 Infinite Reboot Loop

So,
Yesterday I was installing XP on one of partitions I made for it,because I had problems recording stereo tracks for studio on Windows 7( in my previous encounters like that,it worked on XP ).After installation of XP it would restart and just give Unable to load operating system and I couldn't boot in Windows 7 because as most of you probably know,XP overwrites boot section of Windows 7( but that's an easy fix with EasyBCD ).Now I tried fixing the problem with Windows 7 installation DVD and startup repair but no use,then I tried MBR tutorial and it got me to splash screen,but that's where my infinite loop started.Then I tried doing backup with command prompt as in one of tutorials here: Startup Repair Infinite Loop Recovery but no results unfortunately.Does anyone know what to do from here? Or am I going to be forced to do clean install? I temporarily installed Windows 8 Release Preview on XP partition just so I can do stuff until Windows 7 is fixed.

Thanks alot!

Hello vChaser and welcome to Seven Forums.

Sometimes things get so badly messed up that a clean install is the best way to go. But you might be able to avoid that if you can roll back your computer to a date/time prior to these problems with a system restore point.

System Restore

Another possibility is a repair install. It may be able to fix your currently installed Windows 7 and preserve your user accounts, data, programs, system drivers, etc.

Repair Install

Thank you!
Well,I already tried system restore and it didn't work,I was lucky to even make it,but since I was trying to install Mac few days ago I made it just in case.:P

I moved all of my account files to an external disk and program files(x86),just so I can quickly re-install drivers since some are located there and do clean install.

Well,thanks for your help anyway!

Sorry I couldn't be more help. Under the circumstances a clean install is probably the best option. I'm sure you're totally familiar with the procedures but these two tutorials may offer some helpful suggestions.

Clean Install Windows 7

No problem man. I'll mark it as solved,and can be closed if that's okay.

New problem occurred,I did clean install of Windows 7 and when installation progress restarts computer it would get me to boot manager of Windows 8 where I pick Windows 7 from list,but after it restarts again it just takes me to automatic system repair which is useless pretty much only thing I tried was system repair but no use.

I'm guessing you had/have Windows 7 on one partition ( perhaps C: ) and Windows 8 on a different partition ( perhaps D: or something else ), correct? And when you did a clean install of 7 you formatted only 7's partition? If that's an accurate assumption on my part you may want to consider formatting the entire hard drive and getting a clean slate to work with. Diskpart should work from a command prompt at boot. Unless there's a compelling reason to not want to format the entire drive.

Disk - Clean and Clean All with Diskpart Command

You're totally right,whole HD is 500GB and it was originally split in two disks,then I made partition on D: for Windows XP( now 8 ) and when I was installing it had like 4 partitions:System Reserved,C: ( Windows 7 ),D: ( My stuff... ),E: ( Win8 ),and I formated C: and started installing and that happened.So with Diskpart I'll remove everything from HD and it will be in it's original state? Damn,I'll have to make new backup again or stick with Release Preview. >.<

Small price to pay IMHO.

For some reason, dual, triple, quadruple booting always seems to leave computers with boot issues that eventually lead to premature hair loss, flatulence, migraines, and other assorted ailments. From what I've read, all kinds of problems used to happen when people tried to dual boot XP or Vista and 7. It really did make a difference which one was on the computer first and which one was added later. Same thing with 7 and 8, apparently.

Starting with a clean hard drive and following this tutorial should give you what you're looking for with minimum hassle. (He says hopefully.)

Dual Boot Installation - Windows 8 and Windows 7 or Vista

That sucks to be honest,gotta buy 30 new DVD-s,gonna take me 4-5 hours of plain burning to get it done.
Well,if that doesn't fix it,I have a feeling hard drive is gonna fly through the window. -.-

Thanks for help marsimimar,much appreciated!
