Not booting Win7 bootmanger even from Live USB bootmanger

May 15, 2013 at 01:31:28
Specs: Windows 7, 2.2Ghz/2Gb
This thing has given my headaches for months now! This is a triple OS system : win7 XP and Win8. It has a system partition for the boot files.Win 8 is installed in a logical partition, Xp and win7 in primary partitions. Sometimes the win bootmanager is gone, only a blinking cursor.
I think this happens a unclean shutdown in Win8, f. ex. after trying to hibernate or sleep when battery is critical, it's almost useless (only 20% left).

I booted from a Linux Live USB stick with a Plop bootmanager ( a great tool to have!!) and selected the system partition (1st part) to boot from, which under normal circumstances boots into the bmgr, but gave me the same black screen wt blinking cursor, hmmm annoying.
I can however,using Plop bootmanager, select the XP partition (3th part) to boot from and this works becoz it has the Xp bootfiles on that partition.
The only way I succeeded to awaken the WIN7/8 bootmanager was to boot from a USB WIN8 install stick I have. After getting the first screen where it asks if I want install Win8 etc I shut down my notebook and reboot, it did NO REPAIR but the bootmanager was back!!!
1. Does Win 8 block the bootmanger after restarting?
2. How to boot into win7 or 8 if this happens again? (without using the Win8 install disk)
3. Anyone used another bootmanger apart from winbootmanger that resides in the MBR?
THX in advance.

In my experience with dual booting, the latest windows wants to be on the first partition. Then again, I never had 2 versions of windows on the same machine. You could try to install Windows 8 on the first partition.

Although it can be done several different ways, it's generally best to partition & format the HDD in advance using 3rd party software, not a Windows disc. Then install Windows in order of oldest to newest, so XP > Win7 > Win8. Install XP on C:, then install Win7 from within XP & direct it to install to partition 2, then install Win8 from within XP & direct it to install to partition 3. Hopefully that will prevent any hidden system partitions from being created.

I agree w the 3rd party partition program but the newest OS should be on the first partition, not the 3rd.

The dual/triple boot works fine most of the time. The boot process is interrupted only under some conditions unknown to me but always after using Win8. The location of the win8 system is not the problem. Thx.

I do not need to reinstall the OSes. There are no hidden partitions, I can access all partitions from any OS. The problem is that the bootmanager does not show sometimes. This can be fixed by inserting Win8 install CD/USB but is annoying and time consuming! I wish I could tell you more when it exactly happens.
I suspect Win8's hybrid shutdown or hibernation is the culprit. Is that the case?
Is win8 bypassing the BIOS??
(This system is not a UEFI system as far as I know)

BTW The system partition (185Mb), first part., has all the boot files needed and is IMO the best way to setup a multi OS system, it always allowed me to correct boot problems in the past (using USB sticks) and allows me to delete partitions or restore an image without causing problems to win7 or win8.

If you think hibernation is the problem, disable it. I don't see how it can be bypassing the BIOS

The hibernation was the first thing I disabled, still the same problem, that's why I think maybe the hybrid shutdown is the cause, but really just a guess.
I have read the post but this is not really helping me. The problem is a black screen with cursor, no bootmanager! I can use plop or any other boot manager booting from a usb stick. If I understand correctly, what they do is chainload to the boot file residing on the partition selected. Once the first part. (system reserved with win7 bootman) is selected it stops with a black screen. If I select the XP partition (from PLOP) which has NTLDR and bootini etc, I can actually boot into Xp. Which makes me believe the win8 blocks the bootprocess in same way.
Does this makes sense?

Then let's go back to the actual drives in, the machine. How many physical drives are being used? In other words, how many drives can you hold, in your hand?

The next question is, how are they divided logically.? If you boot to one of the OSes & go to disk management, what do you see & do you see the same in all OSes. Also, how does the BIOS read the drives?

One single HDD (notebook): 3 prim partitions: 1. system reserved 2. Win7 3. Win XP
Then the extended partition divided into 3 logical part of which the 2nd part has win8 installed.
The Bios reads USB devices, CD, HDD.

SDAC is the usb stick I used to boot into linux, which has this nice program Boot Repair. ( not that it helped in my case)
Hope this helps.

Plop Boot Manager 5.0.10 released. I fixed a small bug. Booting the 2nd, 3rd and 4th logical partition was not working.

What version of Plop are you running?

@guapo Are you the developer of Plop? Very nice bootmanager! I love it.
I'm running 5.0.14! Sorry for the late reply!

I am not the dev of Plop. That was a quote from his web site. Windows always wanted to be on the first partition & always considered the latest to be the greatest which we all know isn't true.
