Windows needs that to work. Don't do anything with it...
Use windows backup, and create a "recovery disk"
Or, the best way is to buy a copy of Acronis, and use that.
Note: software written before about 2010 probably won't byte-align your partitions properly - and that will kill performance of SSD's,. and shorten their life.
Will the partition that's been moved on to the SSD be aligned?
So what happens if you put a new hard drive in and get the message, it has never had an operating system on it.
If you mean ''BOOTMGR (boot manager) is missing' message. I think because it is generated thru BIOS or UEFI on the Motherboard and nothing to do with a drive...
Sort of, BOOTMGR missing is saying the system can see an OS but the BOOTMGR isn't there or is corrupt.
Intersting, I have an Asus N10J, I wanted to do a clean reinstall of Windows 7 so I removed the hard drive and formatted it on another computer using a docking station. I reinstalled the drive and tried to load windows off a USB ext disc drive (after setting the bios to boot from the drive) and got the "bootmgr missing" message. I tried another hard drive I had lying around and get the message "no OS found", can't win.
Any ideas, thanks.
You might need to set the partition to active.
Thanks for the info, I'll remove the h/d and and try that.
I set the partition active on both the hard drives and no difference, one still says the boot mgr missing and the other does nothing. Before all this I was able to reinstal windows on this netbook, but decided to do a clean instal and thats when I had problems.
wait wait, you put a new drive in, did you set the boot order in BIOS correctly??
might pay to either change that order so that the original drive is the first one.
though I tend to rather physically change the drive in the drive chain to be on SATA channel 2 (channel 1 being for optical drive usually)
looks like we'll need another Timmy!
nah just kidding - I've always wanted to say that here
They are are not new drives, just the original and a spare that I have wiped, partitioned and made one of the partitions active on each. I have the Windows 7 installation disk in an external disc reader/burner connected to the USB ports. I have gone into the Bios and tried rebooting from the hard disc and the external drive and both give me the same outcome, the original h/d says boot mgr missing, and the spare comes up with a blinking cursor on the screen but won't accept and input from the keyboard.
yea. so you have two hard drives installed.
if you remove the second hard drive, does it still say bootmgr missing?
got a spare pc with skype by any chance? this would be a lot easier as a walk through heh.
The netbook only has one hard drive, I have a second spare one that I have tried also.
Out of interest, I got in a system last night with a bootmrg missing error, after stuffing about for an hour doing an external chkdsk and other checks, I decided to run memtest, one of the sticks was completely fluffed it seems.
once it was removed, booted strait into windows, so it might just pay to test your ram a stick at a time.
No offence intended but that doesn't make sense. RAM doesn't come into play at all regarding BOOTMGR, unless the RAM was so screwed it couldn't process the BOOTMGR loading at all at this point though the system should crash or it shouldn't pass POST in the first place, not just display an error.
I know it doesn't make sense, but, that IS what happened.
I assume something is loaded into ram during the windows boot process.
I've been doing computer work since the 386 days, never seen it before either.
I wasn't calling you a liar. Very strange nonetheless.
I know I didn't take it as an accusation.
and yes, Very strange.
