In general, the brain was already broken and the fingers were beaten off: On the old computer, there was 2OC XP and UBUNTU 10.04, as I started a laptop, the housemates were asked to remove the ubuntu and at the same time reinstall XP. The disk was formatted and installed. The installation went well, everything was copied, everything was installed, well, as usual. But then the system starts loading the XP logo appears, for some reason, blinks 2 times, then a black screen with a mouse. I tried 2 other assemblies, the result is the same, and on the laptop all this works I tried to restore the MBR, it began to load up to the assembly logo, and the computer does not hang, the mouse runs. I decided to install ubunt again, in the hope that GRUB will be able to run XP, the result is that ubunta works fine, it is rude that it sees XP, but with the launch it’s the same black screen.

    If a logo appears when booting, then it's not the bootloader. Rather, the problem with the system files or drivers. We must try to start in safe mode. When loading press F8. In the menu that appears, select secure boot. If it does not work after several reinstallations, then this looks like a hardware problem. I would also try to install Windows 7 and reset the BIOS.

    Still need to try in safe mode to remove device drivers. I had a similar problem on my laptop. After removing the video card driver, the system began to boot. Perhaps the problem is in another device, then you need to remove the driver for this device.

    You can still see the download protocol. To enable it you need to add the / bootlog section in the root of the C drive in the boot.ini file. An example can be found here . Down there is an example of the text of this file. You can also try the / basevideo option if there is a problem with the video card.

    • In safe mode it comes in, I will try to reset the BIOS, although I am sure that it has nothing to do with, well, I will try 7, although it will not really work on this computer P4 and 1.5 Giga RAM - max-02
    • A common cause of black screen are viruses. But according to your words, there were attempts to install three distributions and formatted the disk. So viruses have nothing to do with it. There are two reasons: hardware and software (drivers). There were some problems with BIOS, it was necessary to turn off some settings. If it comes in safe mode, you can enable boot logging in order to understand where the download stops. - komka
    • then you can enable logging downloads - how to do it? - max-02
    • I reset BIOS, as I expected no effect - max-02
    • Did you try to remove drivers? And with the download logging turned out? - komka

    At the first start, the Windows install a driver for vidyahi. There are open firewood they are just there. If in the dispatcher device. there is a driver for vidyahi NVIDIA or ATI you need to remove what would be the standard driver.

    • In general, I did not solve the problem, but nevertheless, 7 maximum (build) went. I summarize the result and Ubuntu and 7 function normally, and XP is not installed for obvious reasons, but refuses to start. The drivers are hardly to blame, I reset the bios, the MBR was restored, it remains only to edit boot / ini, but I will probably leave 7, although I don’t like it - max-02
