I don't have experience with Solaris but heres few hints:
First, please use a more descriping title for your posts. Also, asking for urgent help rarely gets you none.
Second, have you even tried to solve this by yourself or even looked into it?
Google gave this
as 4th option.
Have you seen it? Do you use Solaris GRUB? Do you multiboot or is Solaris the only OS on VMWare?
Little more detail will help us to help you.
And finally you have posted Solaris installation problem question to software section even though there is a section dedicated to Solaris.
Posting questions to the right section helps the right people to find your post and to help you with your problems.
Don't take this the wrong way but some forum-manners increase the chance to get help.
And welcome to LinuxQuestions.
