Edit: Starting with Probably not is a bit misleading. What I mean here is that you probably DON'T have to format, and that you probably CAN get it to boot. I was thinking ahead of myself a little, apologies.
Second Edit: You say that you cannot boot into it at current time. What is displayed? The typical "BOOTMGR.SYS IS MISSING PRESS CTRL+ALT+DELETE TO RESTART" ? Does it take you to the "Startup repair (Recommended)" and "Start Windows Normally options?" Does it simply say "Boot media is missing. Press Any Key to Try Again"? (I know my quotes aren't exactly what it says, but generally close enough to understand what I mean). Does it do something else? Each screen is pointing to a different cause. If it begins to load windows then restarts, or you get a BSOD that flashes (or stays) then you're dealing with a boot process issue, most likely driver related. If you get the BOOTMGR.SYS screen, then that's simple. Windows is there, but it doesn't know how to boot. The car is running, but there's no one there to drive it, basically. If you get Boot Media is Missing, well.. At that point the drive is not recognized as bootable. That can either be simple to fix, or hard to fix, depending on why it is not recognized as bootable. It could simply be partition flags. It could be that the drive is not capable of booting, having that part of the partition/system be corrupted/deleted/destroyed. Everything below this is pointing at the BOOTMGR.SYS error, although it may also solve the crash while loading Windows error. With more info, I can give better answers ^.^
Probably not. It could be that the BCD or the BOOTMGR.SYS files are corrupted/missing. There are a few solutions to this. One is to install a form of linux on the drive. Make a.... 10gb partition. Install Linux Lite or Ubuntu or Crunchbang or any other distro that installs GRUB during the install process. GRUB is an opensource bootloader. The only issue with this is you lose the windows bootloader. So the convenient "Press f8 for advanced startup options" disappears and you would now have to use GRUB's built-in command line interface to go into safe mode.
The second solution is to find a WinPE to fix it for you. My two favorites are Paragon WinPE, which is only legally obtained through purchasing Paragon Hard Disk Manager and downloading the additional files that are available through their website. Oh, right, second favorite. Hirens Boot CD. It comes with a FREE Mini Windows XP which has some boot correction software built into it. The only issue with these two methods is that you need to have something to repair on the drive.
There is a third option. I've had to resort to this before, and sometimes it can be a bear to do. Get a windows 7 install DVD. Get the BOOTMGR file from the main directory. Copy it to C: (or whatever designation your SSD has). Boot. Not guaranteed to work everytime, but it's saved my bacon before. The only downside is you're now stuck with the Windows 7 Install animation as your boot screen instead of the pretty windows icon pulsing at you. Atleast that's the only downside I've experienced. The reason it can be a bear is sometimes the drive you're trying to copy it to really, really, really, REALLY doesn't want you to copy it. I assume it's a built in windows thing, manually over-writing bootmgr.sys is a big no no. No amount of yelling at my computer or offering it cookies did the trick. Neither did going into command prompt and using every command I know. Your best bet if you pursue this method is to use a linux distro as an intermediary to copy it for you.
