Windows 7: "Bootmgr is missing" before I can install W7

Win7 Ultimate, x64
 
 

I'm late to the game I know, but it seems to me that a drive that will boot from a CD and not from a DVD is having internal problems that may be corrected with updated firmware. So, I'm thinking flashing the firmware in the Samsung SH-S222A might fix the "I won't boot a DVD" problem for that drive.

I think I would try the new firmware first. If it boots the DVD, then you're golden ... no?

Hey Scott,

Good points. You might be right. It will be easy enough to check. I've already gone through the firmware upgrade experience on my XP box.

I had more aggravating experiences with this machine than I reported here because they were off-topic. And now, thinking back, I suspect they were all due to this drive: When I was unsucessful installing Win 7 in the beginning, I figured, well, maybe I can get the DVD to run if I try installing over an old OS. So, I tried Win2000 at first, and it hung on "Setup is starting Windows 2000". Then I tried XP. Stopped at "Setup is starting Windows." I tried every conceivable variation with my hard dive -- formatted, unformatted, unallocated, boot flag set, or not, you name it. None of it made a difference. And it was puzzling because Win2000 used to be on this machine. But the DVD drive was not. It's worth noting that Win2000 and XP are not on DVDs, but CDs. So, I'm reasonably convinced that all these problems I've been having were due to this drive. Will a firmware update fix it? Who knows, but I guess it's worth a shot.

A general comment about performance on this old machine: I'm surprised that things are as snappy as they are. Originally, I had intended it to have a gig of RAM, but I discovered as I was configuring the box that one of my 512mb sticks was bad, so I ended up using one 512 and two 128s, for a total of 768mb.

So, even though the machine is operating below the minimum "requirements," performance is quite good with a minimal number of tasks going on. It's almost as good as my notebook, which has a dual-core Intel chip and 2 gigs of ram.

Similar problem - Fixed/figured out

I was also getting the 'Bootmgr is missing' when loading a fresh copy of Win7 on a NTFS formated drive. My problem was simple really, it was asking me to hit any key to load from CD/DVD and nothing ever happened until I hooked up PS2 keyboard! The problem was as many times as I hit any key, it was not recognizing the USB keyboard that was connected!!!! ARGH!

Hi Msunderl,

Enable the 'Legacy USB' device support option in your BIOS, that will fix the problem and allow it to recognize your USB keyboard

Hello, first sorry for my bad english
well, I have got the same problem. I bought a new computer without OS, and when I boot from the DVD of windows 7, it show me the message "bootmgr not found".
When I boot from the CD of windows XP, it works fine.

Now I tried booting the DVD of windows 7 from a work computer, and it work fine also !!!

Then,
1- The problem is not from the DVD of windows 7 ( it work from another computer )
2. The problem is not from the PC or DVD as I can boot with the CD windows XP

Maybe
1- my computer can not boot from a DVD ? why as the computer is new
2- my DVD lector have some problem of booting with DVD for some reason.

thank you for your help

Like others have already said in this post, that error message is indicating that your computer is not reading from the setup disk, but rather from your blank HDD. What you need to do is "trick" your computer into reading from the installation disk, even though for whatever reason it doesn't want to. Here's how:
- Enter the BIOS and change the boot order to first boot from your CD/DVD drive; AND for now, disable the rest of the boot devices. ONLY leave the CD/DVD drive as your ONLY boot device. Save and exit the BIOS.
- Now for the trick - take out the installation disk before the computer has a chance to "read" from it. It actually wants to skip over it and read from the HDD (as that pesky BOOTMGR error indicates).
- The computer will now give you another error saying: "DISK ERROR - PLEASE INSERT" or something along those lines. Anyway, nows the time to insert it. Do it and press ENTER. Then it will say again to press any key to BOOT FROM DISK. Do that. There ya go..... off to the installing... follow the prompts. When your done, dont forget to change your BIOS back to have the HDD on your BOOT list.

Hope this works - Take care....

How to set BIOS to boot DVD: http://pcsupport.about.com/od/tipstr.../bootcddvd.htm

If you have set up your BIOS correctly to boot from DVD (not CD) drive and receive the prompt to "Press any key to boot from DVD" and still get the error then you'll need to check your ISO integrity and/or burn another DVD using ImgBurn at 4x speed.

Try also booting the DVD using one-time BIOS Boot Menu key:
Asus - F8
HP/Compaq - Esc
Sony - F2
Acer - F12
Gateway - F10
eMachnes - F10
Toshiba - F12
Dell - F12
IBM/Lenovo - the blue Thinkvantage button

Try writing the ISO file to flash stick using UltraISO trial version: on File tab Open ISO, on Bootable tab Write Disk Image, Format, Write. Boot under USB or HD's.

If you confirm on another computer that your installer is intact and working, then your OD may need replacement, flash stick may need written by another method, BIOS may need updating, or reset the CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

If all else fails, you can wipe the HD using free Partition Wizard bootable CD which will autostart on it's own.

Then the Win7 DVD should also autostart to begin install.
