Cannot Boot Win 7 RC From Vista Boot Manager
Jun 25, 2009
I had a dual boot system with XP Pro and Vista Ultimate 32bit everything was great.
I decided to try the Windows 7 RC but I needed a new drive due to lack of space.
My original drive is IDE, I bought a SATA drive and moved the OS's to the new drive.
I wanted to keep the old drive in system for storage so I formatted it and changed BIOS boot priority.
After fixing some minor issues with drive letter assignments due to the fact the bios reads the first and second IDE channels first then SATA.
I was all ready to install Windows 7 RC on an unallocated 100gb section of my new drive.
Note: that the old drive has a single partition formatted NTFS but is currently blank.
And I did follow the "Golden Rule" of installing the oldest OS first when I set up the computer in the first place.
The Install went fine.
Now for the problem.
Windows 7 did not add an entry into Vista's boot manager so no option to boot into Windows 7 without the install disk in the drive.
I used EasyBCD 1.7.2 from within Vista to add an entry for Windows 7. But when initially added easyBCD assigns the drive partition a drive letter that I don't have.
Therefore the entry does not show up on reboot. I changed the path to the correct drive and then the entry does show up on reboot.
But when I select Windows 7 the boot manager refuses to load Windows 7 saying that "cannot verify the digital signature of the file winload.exe"
I have tried wiping and re-installing the Windows 7 partition 3 times I've tried using the Windows 7 install disk to repair startup problems.
None of these has worked I'm at a loss as to what is happening.
If Windows 7 created a hidden partition for recovery and boot files I'm unable to find it, I thought of trying and Linux Live CD to look for the hidden partition but have not done it yet. My thought was to delete this hidden partition and wipe the Windows 7 partition and format it before re-installing either from within Vista or during the Windows 7 install process via a command prompt in an attempt to keep Windows 7 from creating this hidden partition. The problem is that I don't believe this will solve the problem due to the digital signature error reported by Vista's boot manager.
Can anybody help me with this or at least bring a perspective that I may be over-looking?

how to re-write the information ( what and where) so that I can access the hidden partition on a laptop running Vista so we can put the system on again. I ask because Alt+F10 no longer worksIT DID work a few days ago, and we put Vista back on because the machine had been infected with malware which shut off all the services. So, restored, all sorted and the machine went back to my son working fine, but then a couple of days later, Service Pack 1 tried to download and install via Windows Updates, and kept on trying and trying, without completing.My son brought the machine back because he could not get it to reboot, and we found the system was corrupt so that we could not repair even after chkdsk.

If you've been using Windows XP for a while now and want to try out window 7 or vista, you might have tried dual booting! In that case once you installed windows 7 or vista, you may have noticed that your windows XP entry has disappeared. But do not worry. Your windows XP is still there. The only problem is windows 7 just overwrote the windows xp bootloader. This is a easy fix. Just follow the steps below.
Open an elevated command prompt (Start > type "cmd" > right click on "cmd" > run as administrator)
To create an entry for Windows XP type the following. You can replace "windows XP" with any name that you want it to show. Code :bcdedit /create {ntldr} /d "Windows XP" Now specify the partition where windows XP is installed. Here I have used my E partition. Choose the partition (B, C, D, E, F) where you installed your XP. Code :bcdedit /set {ntldr} device partition=E: Now to set the path type... Code :bcdedit /set {ntldr} path tldr Type the following to add this boot loader to the boot up screen. Code :bcdedit /displayorder {ntldr} /addlast
Restart and you are done!
If for some reason you get an error and are unable to boot into windows XP, then get back into your windows 7 installation and download the boot files from [URL] and paste it in your WIndows XP partition's root directory. [URL]

I'm having a problem every time I power on the system. I'm dual booting vista ultimate with win 7 build 7100; with vista I have no problem, but with 7 every time I start the system the first boot attempt gives me the error 0xc000000e after the boot manager display: "the boot selection failed because a required device is inaccessible".;after a reset the system boots 7 with no problems. Win 7 is installed in a brand new hd(seagate barracuda 1.5tb) and vista on a second hd.
I've search the web for people with a similar problem with no success. I've tryed already many solutions but the problem persists(latest bios for the motherboard, latest intel sata drivers, etc). I'm hoping that this could be a bug in win 7 instead of a hardware failure for the hd. Again, the strange thing is that this only happen after the power on. After that first error, no matter how many reboots, the system always boot without problems.

For some odd reason, after doing some changes to my partitions in Windows 7 and restarting my computer, I got the ol' "BOOTMGR is missing" message. I have the Windows 7 Repair Disc image file and a 4GB USB Flash Drive, but, sadly, no CDs. Is there any way that I can put the image file onto my USB Flash Drive and boot from it with my Acer Aspire X1200 desktop computer?

My system dual boots to either Windows 7 or Vista Ultimate, or, at least it is supposed to. Something happened and now the system just boots to Winodows 7 without giving me the choice to boot to either. When I use F6 I find that only Windows 7 is listed in the Operating Systems box.

New laptop has Windows 7 Home Premium 64bit. I have two business programs that won't run on a 64bit system. Partitioned the hard drive to install Vista Home Premium 32bit to create a dual boot system solely to run these two programs.Can't get Vista to load. Followed tutorial meticulously. All goes fine until the "Vista will boot for the first time" step. After this first boot, the screen returns to the "completing installation" page. However, the process dies here and the progress bar across the bottom of the screen never moves, even after an hour. Reformatted the partition and started over with same results. Multiple attempts always die after the first boot.

I have two drives (C and D) with Vista on one and Win 7 on the other (not sure if they're actual drives or partitions of a single drive, how do I tell?). I am dual booting and never use Vista. Starting to need the disk space and want to delete Vista. Is this difficult in this scenario?

I had recently installed windows 7 on my laptop running windows vista. I did not remove the existing windows vista installation, and thus win 7 was installed in a dual boot combination. Now, i want to remove vista from my laptop and use windows 7 only.The problem is that during installation, win 7 was installed on logical drive and windows vista was on the primary drive. Thus, i cannot delete/format the windows vista partition. Also I cannot transfer the boot drive to the partition containing win 7 because the vista partition is the active one.

I find that the Windows 7 boot screen slows down the boot process on my machine. Is there a way to restore the old Vista scrolling loading bar? I know it's there as my netbook uses it.

In attempting to install W7 64 on generic non-micro ATX [full] form factor desktop, Windows 7 will successfully begin installation. Upon reboot to complete installation I am informed that the boot manager cannot be found. How might I determine what is wrong so that I might correct the problem? Might it be a problem with jumper pins? No-o-o-o, it's not IDE HDDs I'm using; it's ATA. Might Microsoft's installation disc be at fault? I'll try using a different 64-bit disc with the [legal] new license, and then a 32-b it disc with the [legal] new license, but I'm at a loss. If it were the processor, it wouldn't even get to the install GUI that originates from the disc, would it? Otherwise, I'll have to take it to the shop and pay them to do a RAID 0(striped)config/install. The reason I'm posting this here is that I strongly suspect the 64-bit edition discs to be inherently flawed. On my 64-bit processor laptop, the 64-bit disc wouldn't install, but the 32-bit one did. I never worried about that because all I'm using on it are 32-bit apps. It's only on the custom-built desktop I need the 64-bit environment.

I tried to install WIN 7 to a NEW HD (clean install) since you cannot do a WIN XP upgrade install. I left my old C: drive (WIN XP) hooked up while I installed WIN 7 to the NEW drive. Afterward I decided that my computer is too slow to effectively run WIN 7 so I took the NEW drive out (WIN 7 installation) and intend to put it in a new faster computer.Now when I try to boot up my old C: drive with WIN XP, I get a WIN 7 Boot Manager. What a PAIN in the A--. How do I get rid of the Boot Manager so my WIN XP will boot up normally?

When receiving this message on boot up attempt running windows 7 home premium on a dell 1545 laptop with a fresh install and new hard drive would the problem be hardware related or software? Any chance it could be hardware related to the motherboard or is it most likely software related to the OS install?

I have a problem thaI am hoping someone has a solution to. I had previously installed Windows 7 RC on my computer. I then installed a SATA RAID PCI card and also installed a second HD. I attempted to install Vista on the second HD, but had problems and uninstalled it. When I try to boot up the boot up screen gives me the option of Windows 7 or setup. If I choose Windows 7, there is no problem. If I do not choose and the boot up continues in the setup mode I get an error message on the blue screen of death.
The computer shuts the start up in order to preserve the computer. It instructs me to remove the PCI card and HD and reinstall them. I have done that. I undertand that the boot up files fromVista are still on the the HD in a hidden folder. How do I correct this situation? Can I re-install Vista on the second HD and achieve the desired result? I formatted the second HD after the blue screen, but should I use a drive scrubber and remove all traces? If you know or believe you have an answer, I hope to hear from you.

Firstly i'd like to mention i've never used dual booting, i've never ran more than 1 OS on this computer...
When i start up the computer i get the dreaded "DISC BOOT FAILURE" message.
IF i have the Windows 7 or even the Vista dvd in my primary dvd drive i don't get that message and i will load into windows.
I've been having this problem for ages now, even when i was on Vista before i formatted to 7 a few days ago...
I thought formatting would fix this problem but it hasn't, it seems it is still not finding the boot manager...
I've used EasyBCD to check the installation of the boot manager and it says everything is there and nothing is corrupt...
I've even tried reinstalling the boot manager...
Nothing is working, this is really getting on my nerves now lol as it takes me ages to boot into windows and i'm not very patient when it comes to rebooting .

Can anyone help please? I added another drive to my computer today. I am dual booting Windows 7 with Vista x86 and I was using Acronis disk manager to format the new drive and it asked me to reboot. After this is where the confusion started. My windows 7 got stuck in the windows splash screen. I had to install the installation disk to start it. After this it seemed fine until I rebooted into Vista to make sure that it was okay and it appears that acronis was completing it's disc management within this.
It booted fine into Vista but my boot manager shows 2 versions of vista instead of default Windows 7 and Vista.

I did a dual install on my desktop (Windows 7 home and Win XP clean installs on separate (sata)HDs with the other HD disconnected during install of each OS). Technically it's a triple since I have Linux Mint Debian on a third, thumbHD (same disconnect procedure there). I expected that to run smoothly. Well, it did the first few times, I could bring up the boot options (Esc on this one) and choose what drive to boot from. And a little while later this darned meddlesome win 7 boot manager shows up at startup and asks me what OS I want to boot from. I have to hit Esc real quick and bring up the boot sequence to chose what HD to boot from instead.
Because if I play along and choose an OS from the list any boot option but the Windows 7 fails. Any way I can get this meddlesome thing off my back? (It's like the good old annoying Office Assistant.)
(If I truly wanted this option, I'd probably install EasyBCD. I used that when I dual/triplebooted a couple of old laptops a few years back, and it was fairly nice. But right now I just don't need it.) I looked into BCDedit, which I am not terribly familiar with, but I couldn't quite find an option to shut down the BMS. (And I know better then to start deleting entries in there without proper backup. Barely, but still.)

I use XP on my machine with two 300 GB HDs configured as RAID1 (Nvidia NForce 570 SLI). There are two partitions C (100 GB) for system and D (remaining 200 GB) for data. All is working fine.
Now I try to install Windows 7. First I resized D by 100 GB and installed Windows 7 on this new partition. I updated the Nvidia NForce RAID driver and can see correctly my RAID under Windows 7.
My problem now is that if I start my computer always the old XP boots up.
The Boot Manager is not present. The only way I can boot Windows 7 is to insert the
Windows 7 installation DVD (and not pressing any key) then Windows 7 is booting.
The boot manager is present but only on this new Windows 7 partition. I already tried (using EasyBCD under Windows 7) to add the old XP as a second entry in the Boot Manager but I was not able to boot XP using the boot manager.
I see the XP-Partition under Windows 7 and vice versa but it seems to be impossible to use the boot manager.
How can I install the Windows 7 Boot Manager on my XP-partition, thus I will be able to
choose whether to boot XP or Windows 7.

I have a system running XP. I partitioned my drive in half and installed Windows 7. I tried to start XP again and messed it up. I think it's trying to use XPs boot manager. Do I need to re-install 7 to use it's boot manager?
Now that I know this .iso works great, I want to put 7 on a partition on my main Vista system. I can't afford to lose everything like I did on the XP system. When I tried to start XP after installing 7 I got an error. "windows root system32 hal.dll is missing or corrupt"
I can't have that happening to my main system. Is this normal? Did I do something wrong? Will it happen to Vista?
