Long story short, got 128g SSD with my PC 1 year ago after a few issues i upgraded to 256g SSD and was to send the 128g back but ended up buying it as well. Run my 256g SSD for a year and i managed to get some annoying pop up on it (probably from porn sites ill admit) Googled that and no real answers onto how to remove it so thought ill do what i wanted to do with the 128g and use it as my boot drive and put all games on the 256.

I reloaded windows 7 pro onto my 128g SSD. All went fine but i noticed i had a 100mb partition on (this possibly comes from the OC build of my PC?) So in management i disabled this as primary and made the other partition with windows install on it primary ? Appeared no problems.

Had to do a reboot for some reason and got the "no boot manager" screen of death, googled on other machine and told to create boot disk etc etc but no joy, windows was having a proper paddy on and wouldnt repair or anything :rolleyes: Even using command prompt it wasnt allowing me to change boot form CD.

In the end i had to change bios setting to boot from disk so i could reload windows 7 pro again, in that process i deleted the partition and formatted the 128g SSD and installed windows with no problems. Rebooted numerous times now to reload updates etc.

Just after some answers really i have installed a few windows in my time going back to 2000/XP but not really a computer know it all if you know what i mean. Windows 7 has always been a doddle in my terms, vista used to take 4-6 hours i can pop windows 7 on in about 2 :rolleyes:

Why was 100mb partition put on originally?

Why did disabling 100mb partition break boot up?

Why didnt the PC see the windows disk in the CD bay and boot from that?

Sorry if this all sounds a bit nooby but never really had this problem before :(
 
I believe the 100mb partition is related to Bitlocker and is required. As you just removed it without really thinking about it you removed the bootmanager which caused the issue you experienced.

There are tons of sites on this and a quick google will show you. For future reference though I wouldn't be deleting partitions, etc. without having a good look around first.

If you're having weird popups, etc. then the best way is to format it and stop going to dodgy sites! :D

So:

1. Bitlocker / Bootmanager
2. You removed the bootmanager
3. Probably boot order in the BIOS - you still had a bootblock (i.e. you hadn't removed the MBR) so the BIOS thought it could boot but once it got past stage 1 it failed.

That 100MB partition is a system reserved partition and contains the boot manager which is the information the computer uses to determine where the OS is located and how to boot. This is why your computer failed to boot once you deleted it.

You can take a look at what's on it by opening an elevated cmd prompt type:

diskpart
listdisk
select disk [number of your os drive]
list partition
select partition [number of the system reserved partition]
assign

You'll now see it in My Computer and if you enable show hidden files and folders you can see what's on it.
 
I understand now i shouldnt have removed it but whenever i have done windows builds before i have never needed or had 1 but because the partition was put on the 128 it showed up as a drive and i have never had a partition drive before unless i asked for it.

I dont have 1 now since i formatted the 128 SSD on windows start up. it now boots up from the 128g with no partition, was sort of why i posted if you get me.

Dont get me wrong i know what i did but i never seen a boot partition before on any build either i have done or my mate has done for me, just confused me a bit.

Live and learn thanks for replies :)

Haha

I know how to get to the Disk Management thats what got me in trouble in the 1st place. My problem was i didnt want the partition so tried to remove it.

Lucky enough id only just build the thing onto the 128g so wasnt to hard to just reload apart from you dont get the option to reload from windows and DL all the updates 1st think i had to DL 150+ updates last night whilst beating myself up at the same time for being a tool :confused::cool::p
 
But i never had 1 before, you get an option for when you load windows to put a partition on and i didnt want it but didnt realise it would have had the boot up manager in it ;)
 
If you have a hard drive with no partitions on it (ie, a new one or a formatted one) Windows setup always creates the 100mb partition; it's pretty widely documented, also tells you during the setup that it will create one.
 
When you install Windows and create your first partition Windows also creates this extra partition and it warns you that it does. It will show up only in disk management as system reserved and you should just leave it alone. Mine in Windows 8 is 350mb.

If you had windows 7 then yes you had one, you always one, you just didn't know it was there, then you found it, then you deleted it, then you broke your computer by removing something that was always there and you didn't realise.
