Windows 7: Win 7 bootloader failure

Win 7 bootloader failure

Hello everyone,

I got serious problem and don't know what to do. I have notebook Fujitsu Siemens Amilo Pi 2540 with Vista Home Premium preinstalled. There are 3 partitions on disk: C system, special reserved partition for recovery and D. I installed Win 7 Ultimate. Everything gone fine, but after restart following happens: computer stuck in cursor screen without any error message and boot nothing. Booting from USB or DVD doesn't work. I have removed disk and put it in external reader. I formated C partition. Result is the same. Computer doesn't boot any way.

1) Is there any possibility to recovery old Vista form recovery partition?
2) Or is there any option how to rewrite bad bootloader?
3) Or what else can I do to let my computer boot?

Thank You very much for any answer.

First you would get more response for a vista OS on vista (vistax64.com) but.

Do you have a working Vista dvd? It works on another computer?

Ifr so boot from the working dvd (not a restore dvd). What happens?

Where did you get Win7? If you burned it yourself, check ISO integrity and burn another DVD using ImgBurn at 4x speed. Or try install from USB flash stick: YouTube - How to install Windows 7 from USB (WinToFlash)

Make sure you have the latest BIOS update. If so, reset the CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS
Then set the SATA controller to AHCI first, IDE if necessary.

Remove all but 2gb of RAM to try install. Unplug all other HD's and peripherals.

If this fails, I would run Recovery using the steps given in your Manual which you can read on the Support Downloads webpage for your computer model, or in the setup literature which came with computer. You should have made Recovery Disks when setting it up as Recovery may not even run now. If not:

Quote:
Recovery from the Hard drive
Tap F8 - choose repair my computer. after your password make sure you choose the bottom option from the menu and then select "from hard drive"
Once you run Recovery, make the Recovery disks then wipe the HD of conflicting code to clean install Win7 after completing the earlier steps: SSD / HDD : Optimize for Windows Reinstallation

I know but it is qustion between Vista and Win 7 so I didn't know where to write first. I don't have working DVD with Vista because there is recovery part on disk which may content Vista files and because there was Vista preinstalled when I bought the computer. I have functional bootable DVD with Win 7 from which I installed Win 7 Ultimate. But now, after restart, it doesn't boot from any resource anynmore.

I burned it normaly with burner integrated in Deamon tools. I was able boot from it without problem, so I could installed Win 7. So I know that DVD is burned properly. The problem is that now after restart it doesn't boot from any resource: USB, DVD or disk. There is no response and no error message. I didn't try to reset CMOS yet, so I will and I'll write what happend. And that trick with removing RAM, it looks interesting, I'll try it too. Thank You both, You gave me new hope.

Because the DVD will boot doesn't mean it is burned correctly. Use ImgBurn at 4xc speed to burn ISO.

WHere did you get the ISO? Have you confirmed the HASH or downloaded another copy to try it?

These steps I have given you are not "tricks" - they are the known procedure to overcome install failures. Try each step in order and report back on each step, so we can answer your questions or give you futher help.

It is done

Everything gone different. You probably were right about bad DVD integrity, because my DVD drive is broken and whole data from D are lost. Now I got Linux so maybe something better. I have one more qustion. How is that HASH done? It is very good to know how to check the similarity of two produscts but I dont know how to do it. Thank You very much for advice and Yor time.

HashTab

Windows 7 RTM SHA-1 hash - checksums

The bad burn or ISO wouldn't break your DVD drive. It may have been the problem to begin with.

What was D and how did you lose it?
