CDBOOT: Couldn’t find BOOTMGR

Situation : 2 brand new systems made from new parts. First PC installation went smooth, the second wouldn’t boot from the Windows 7 DVD.

I tried the other installation disc (from the first system), but i got the same message.

CDBOOT: Couldn't find BOOTMGR


Part Description
1 CPU Celeron G350 Celeron G530 SandyBridge 2.40GHz 2MB 2C TDP 65W LGA1155, 32nm
2 RAM 2 GB DDR3 Kingston 1333 DDR III 2GB, 1333 MHz, CL9, Kingston ValueRAM single rank
3 MB H61M-DS2V Intel H61,S1155,Integrated + PCI-E 2.0, PCI-Ex16 ,DVI.2XDDR3,2*PCI-E x1,8XuSB2.0,4XSATA2,LAN 1000 Mbps Dual Bios
4 HDD 500 GB HDD WD 500GB WD BLACK, Serial ATA3, 7200rpm, 64MB, [WD5003AZEX]
5 PSU 450W Standard PSU found in M298 Delux case
6 OS WIN7 32bit OEM Windows 7 Professional 32 bit OEM genuine

Checked to see if the HDD and DVD were detected in BIOS, changed from IDE to AHCI, reinserted the disk, no luck. The DVD was set as first boot option.

The quick solution was to try another DVD drive (Samsung SH-222BB/BEBE) and it worked.

I’ve read somewhere else that wiping the HDD also worked, but this should not apply here because the HDD’s were brand new.

Anyway after i installed and activated Windows, i tried to boot with the SH-224BB optical drive and SURPRISE : it worked. So it has to be related with the way new drives have space unallocated. Still, in my case there were no partitions on any of the drives. For those who don’t have spare DVD drives laying around, i recommend installing from USB, using Windows 7 USB tool.

    Hey ! i got a solution… when you boot into your CD, it will display “CDBOOT:COULDN’T FIND BOOTMGR” right?
    so what you’re going to do is press ctrl+alt+del and the system will restart.. and when it automatically boot to your CD, your problem is fixed…. hope it helps
