Solved bootmgr problem, system working with win7 DVD

[Yoknee]

how do i detach it?

Open the case and physically disconnect it.

I think C & D are on the same HD thats how they where installed with XP. (as partitions)

Look at your Disk Management Hard disks.

 

[Yoknee]

Your specs are confusing. It says your Computer is home built, but then the mobo says it's a Compaq laptop.

If you have a laptop you can disable the HD in BIOS setup, or move the data off and wipe D now since it's probably interfering anyway and the only way to know for sure is to wipe it. Then you can leave it installed. Diskpart Clean Command

And, yes, you need to have the Win7 HD set as the first HD to boot in BIOS setup. Check that now, or unplug or disable D to be sure.

no this aint a laptop. Its a desk PC.
Ill try to wipe the data off the D.

I'm taking a guess here that the second HD was installed after WinXP was installed. If that was true then

Disk 0 would have had C & D
Disk 1 would have been E

Then you installed Win7 and Win7 assigned drive letters to the Primary Partitions first
Disk 0 primary partition = C
Disk 1 primary partition = D

Then drive letters got assigned to the logical drives
Disk 0 extended partition, logical drive = E

Hope that clears it up a little.

ok cleaned D drive.

thanks, thats how it went yes.

Maximize the Disk Mgmt screenshot so we can see all of the listings.

Did you run Startup Repair three separate times with reboots while only C was marked Active. Yes or No?

Was there ever an OS on Disk1 which is showing as D in Disk mgmt now?

yes, i run startup repair 3 times, only got it done once though, having some lockup problems.

No, ive never hade a Operating System???? OS on disc 1, it has always been just a backup HD with folders and files only.

 

[gregrocker]

Then run the three separate Startup Repairs with reboots in between to see if it corrects.

If there is no boot code on Disk1 you can leave it plugged in, although it would be best to disable it in BIOS so it can't interfere.

 

[Yoknee]

well, its working now. cleaning the D drive up and doing the 3 startups repairs have finaly cured it.

Thanks guys, much apreachiated. special thanks to Greg, keep on surfin m8.

Glad it's solved. Good work Greg.

 

[Kaktussoft]

Glad the problem has been solved. What did solve the problem? Three startup repairs, or cleaning up second harddisk (nothing was on it, only system volume folder and recycle bin)

 

[gregrocker]

Possibly both, or it could have been marking the partition Active if that had not yet been done before Repairs x3.

You need three Startup Repairs to repair or rewrite the System boot files to the partition which MUST be marked Active.

And it's best to unplug other HD's since old boot code can sometimes conflict, so wiping the HD may have cleared the boot sector, too. Bootsecting can remain even with a deleted or formatted HD.

C partition was active all the time. MBR and boot sector were rebuild. System could start using dvd..... very strange!

Other disk doesn't have on active partitition.... still don't understand what went wrong.

Sometimes computer problems are a great mistery

If you know for sure OP ran three complete Startup Repairs with reboots (often not completed) while C was marked Active, then it was possibly interference from the other HD which can retain the /nt60 bootsecting even if it's formatted and deleted, but not if it's Wiped with Clean command. This is why the unplug, which he satisfied by wiping.

We have some cases where the SysReserved partition is also corrupt so that the Active flag needs to be shifted to the Win7 partition itself to run the Repairs, if first it won't start trying Repairs on SysReserved.

You get a feel for these after so many thousand (Today is my third Anniversary here). One thing we've learned since beta is that automated Startup Repair covers more bases than just the bootrec commands which it also automates. However in rare cases bootrec/bootsect commands need running manually if all else fails. Troubleshooting Windows 7 Failure to Boot - Windows 7 Forums

Edit: What a perfect circle! I see our original teacher here SIW2 is in the thread so maybe he'll elaborate on all of this.

Thanx for all the clear explanation. He didn't perform startup repair 3 times I think. But the first startup repair said everything was OK and system was booting fine with DVD inserted. Even bootsector and MBR were raplaced using bootsect.

So I think the second disk is actually the first drive that BIOS tries to boot from(?) Second drive was almost sure the problem. But still I don't understand why it says "missing bootmgr" as this message comes from partition bootsector (not MBR). That partition wasn't active at all!! It looks like MBR thinks it's active

Should replacing second disk MBR and bootsector fix the problem you think? We'll never know

Now I have learned something... never trust my own logic. To be sure it boots from right disk... unplug all other disks.
