Computer Cannot Find Hard Disk Boot Record

Windows Computer Cannot Find Hard Disk or Boot Hard Disk MBR?

"Hello, yesterday, I had installed a Windows 7 OS on my Samsung computer and also replaced my attached old WD internal hard disk with a new Seagate one. However, after changing that old hard disk, the computer just said it could not find boot hard disk record MBR and would not boot up. What does that boot hard disk MBR indicate? How about hard disk GPT searched online means? What can I do now to reboot PC smoothly? Thanks for any suggestion here!"

Hello, have you partitioned that newly replaced Seagate internal hard disk well after removing the old ones? Have you install the new Window 7 version well on this new Seagate hard disk? What type record your new Seagate hard disk is, MBR type or GPT type? OK! If you really don't know or even not understand what these questions are talking about, do not worry. Read this article to learn more and see what you can do to boot up your computer as before.

What the Computer Hard Disk Boot Record Is?

Computer hard disk boot record often talks about the standard hard disk partition table which can decide on how many partitions you can divide a specific hard disk into, how the computer hard disk will read or store the stored or coming data and how the computer will read the loading OS and boot up, etc. And, in these days, there are often two types of boot hard disks, the MBR hard disks (also called as "Master Boot Record" hard drives) and GPT hard disks (also called as "GUID Partition Table" hard drives).

What Are the Differences between the MBR Hard Disks and the GPT Hard Disks?

There are many differences between the MBR hard disks and the GPT hard disks, like:

1). Popularity
On the outside hard disk markets, the hard disk with MBR partition table format often are much more popular than the ones with GPT partition table format since the MBR hard disks has been created and developed for a much longer time than the GPT hard disks.

2). Different partition numbers.
With a MBR hard disk, you are often allowed to divide it into four primary partitions. If you want to have more ones, you are supposed to select one of these four primary partitions as an extended partition. And then, divide this extended partition into much smaller logical partitions. However, if you do have owned a GPT hard disk, there is often no limitation about how many volumes you can divide your hard disk into in theory.   

3). Different computer Platform
Since the hard disks with GPT partition table format have been designed and developed only for several years, the related technology is not as mature as the hard disks with MBR partition table format. That’s also why the MBR hard disks often can be used under nearly all types of Windows operating systems. While the GPT hard disks often can often work well under Windows 8 or upper Windows OS versions, Window Vista and more advanced OS versions. Overall, they do have different computer platforms.  

4). Different Maximum Hard Disk Capacity
Generally, the MBR partition table format often can be used on a hard disk that is up to 2TB in size. However, if you want to use a hard disk with more than 2TB, you’d better choose a hard disk with GPT partition table format, not the MBR partition table format in case of farther troubles.
Overall, they are really different and also requires different computer configuration. People are supposed to choose one from the according to different conditions.
