Если при переносе винта с установленной операционкой (Windows2000 , WindowsXP) на другой компьютер и попытке загрузиться с него
вылетает ошибка 0x0000007B.... то сделать следующее:

На компьютере, на котором устанавливали систему:
1. Выдернуть файлы
atapi.sys
intelide.sys
pciide.sys
pciidex.sys
из %SystemRoot%\Driver Cache\I386\Driver.cab

2. Скопировать их папку %SystemRoot%\System32\Drivers

3. Запустить Mergeide.reg (см ниже) на слияние с реестром

После этого можно переносить винт с системой на другой комп спокойно загружаться :))
