this works , was giving bad substution error when a space was left between billreminder and /D:/ , and i didnt knew before it could work without quotes on strings , also the replacement string (in question) should have been in double quotes to escape /

You can you string substitution if you prefer, but using cygwin you can also use the command cygpath.
This command convert the parameter supplied as path in Windows-style to path in cygwin-style, you can use it as follow:

b=$(cygpath $b)

+1 this is the right way to work in CYGWIN environment, the other answers are playing around only (include the accepted one), which can't identify the difference of windows path (\) and Unix path (/).

You can use this substitution:

s='D:\juno_workspace_x64\9.0.4_app\moneycenter\src\webapp\jsp\billreminder'
echo "${s/D:\\//cygdrive/d\\}"
/cygdrive/d\juno_workspace_x64\9.0.4_app\moneycenter\src\webapp\jsp\billreminder

Simply remove the second $ sign:

~/> echo ${billreminder/'D:'/ '\\cygdrive\\d'}
\\cygdrive\\d\juno_workspace_x64\9.0.4_app\moneycenter\src\webapp\jsp\billreminder

you can do it this way:

b='D:\juno_workspace_x64\9.0.4_app\moneycenter\src\webapp\jsp\billreminder' 
b=\\cygdrive\\d\\${b#D:\\}
echo $b
