after partitioning my c drive( to dual boot) i installed win7. as win7 and win8 were not dual booting, i tried marking the win7 partition as active but after restart my computer now says an operating system was not found. try disconnecting any drives that dont contain an operating system. press ctrl alt del to restart. so i really need help cause its driving me nuts

Insert the Win7 DVD,and restart the PC,once it restarts,get into the BIOS,which you'll be able to do by pressing a key,which varies according to mb manufacturer.Anyway,you can see that in the Splash screen.Get in the bios,and under the boot menu,select the DVD drive as the first boot device.Save the settings and restart.Then it should boot from the DVD.

Well,doing a clean install,formatting the drive would be always better.Anyway,that windows.old can be used to retrieve your old files,if you choose not to format the drive,and install the OS to the same drive with the old OS.

so lets say i marked the partitioned part as active (no important files cause it was a new partition) would it still format from both the partitioned and cdrive? and is there any way to make flash drive bootable (having problems installing os)

Yeah....It can be formatted...
And the way to make usb bootable,there certainly is a way which worked for me.Let me tell you,and,you'll need atleast a 4GB USB drive.
1)Plug in the USB
2)Run Command prompt with administrator rights.
3)Inside the DOS,type DISKPART.
4)Type LIST DISK.you'll see the drives listed,and note the drive number of your USB.Say,for example Disk 1 or Disk 2.
5)Assuming that yours is Disk 1,type all the below commands one by one

SELECT DISK 1

CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ACTIVE

FORMAT FS=NTFS quick
Once format finishes,type these

ASSIGN

EXIT
Don't close the DOS now.
6)Mount the OS iso file,or insert the Disc.I assume your drive letter is D,and USB drive letter is H
7) Type in the DOS,
D: CD BOOT (Note the space after D: )
Then type,
CD BOOT
Next type,
BOOTSECT.EXE /NT60 H: (Note the space before '/' )
where,D is your DVD drive letter and H is the USB drive letter.
Once these are done,exit the DOS,and copy all the files from the Windows OS Disc to the USB. You have your bootable USB,which you can use for windows installation after making the Removable media the first boot device inside BIOS.

(sorry i post here cause somehow i cant create new thread. the case looks similar)

ERROR LOADING OPERATING SYSTEM after "Mark Partition as Active" for C Drive

my dell laptop with windows 7 is giving me problems, so i decided to try backup using external hard drive. However, it has an error on shadow copy, so i searched online to find solutions and i did the following as suggested online (links shown below):

1. SPP Notification Service Properties -> Automatic (Delayed Start)
2. Volume Shadow Copy -> Automatic (Delayed Start)
3. Disk Management -> C Drive -> Mark partition as Active

not only the methods didn't work and didnt backup, now i have a bigger problem.
i switched on my laptop and "ERROR LOADING OPERATING SYSTEM" appeared. i think it has to do with the partition that i changed. i cant enter into safe mode.

so what should i do? is there a way to save the laptop without losing the files inside?
by the way, i'm a technology-idiot so i dont really understand some of the tech terms. any dummy guides please? thanks
