<h3>Symptom 1: "<strong>No bootable medium found</strong>" error screen on startup</h3>
A <b>partition table</b> is a table maintained on disk by the operating system describing the partitions on that disk. This term is most commonly associated with the MBR partition table of a Master Boot Record (MBR) in IBM PC compatibles, but it may be used generically to refer to other "formats" that divide a disk drive into partitions. If the partition table becomes damaged or corrupt, or simply has no bootable entries, then the system becomes unable to locate the partition to boot from and the boot process is halted.

<h2>Causes of this Error</h2>
This error has been known to occur as a result of one of the following causes:
<h3>Cause 1: Partition table is damaged</h3>
The most frequent cause of this error is a damaged partition table. It is located in the MBR(Master Boot Record) of the boot sector, which holds the information on how the logical partitions, containing file systems, are organized on that medium. The most common cause of that error is a failing hard drive, or a disk write error.
<h3>Cause 2: Partition table is empty</h3>
Another possible cause of this error is a partition table that has no bootable entries. This may happen because of errors made when configuring the partition table manually, or disk read/write errors.
