try hitting ESC and see if you can choose the Hard drive to boot

Hi Saravana,

Have you checked if your virtual machine's .vmdk files are available in your datastore?

It looks, your windows boot/MBR partition got corrupted. You need to follow the below steps to get this recovered without any data loss.

a) Set BIOS to boot from CD/DVD

b) Inset your Windows setup CD

c) When prompted select Recovery Console option

d) Now go to C:\WINNT or C:\WINDOWS

e) Next type following command:

fixmbr \Device\HardDisk0

f) But how did I obtained the device \Device\HardDisk0 name? The device (drive) on which you want to write a new master boot record can be obtained from the output of the map command. Type following command:

map
fixmbr \Device\HardDisk0

g) Type exit to restart system

exit

h) Remove CD and boot from hard disk.

Hope, this will be helpful for you.
