hi I have 120gb sata HDD in which i have intalled windows vista. Now i attached another hard disk of 640Gb capacity (and remove previous HDD) and install windows 7 in it. Now again i have attached my previous HDD, now total 2 HDD's are active. But when i boot my computer it recognizes the OS of my 640GB OS instead of my 1st HDD OS. Is there any method so that my computer loads the os as installed in first HDD (i.e. 120 gb HDD) Please reply soon. Eshban
yes, in the BIOS there is an option called something like "boot priority" or something, enter the bios by pressing <Del> or <F1> usually on most systems, and you can select the device to boot from first
Yes, you can resolve this issue by setting boot priorities for your hard drives. To set boot priorities execute the following steps: 1. Press the DELETE key on your keyboard as soon as you switch on the computer. 2. Now, a window appears where you have to select BIOS. 3. Now, use the arrow keys to move up and down to select the drive that you want to load first. 4. After that press the ENTER key and save the priority. 5. Now, repeat the steps to set the priority of another hard drive. 6. Depending on the settings you do, OS will load from the respective hard drive.
yes, these instructions may work on your system but for example Dell are a quite large manufacturer an i know <Del> doesn't allow you access to the BIOS, i wrote quite a good general BIOS post here
