We already saw earlier <\/a>how to boot ubuntu over ipxe with NFS<\/p>\n

Howeber, setting an NFS server in windows is not always a given.<\/p>\n

Hence, lets see now how to do it with a CIFS share i.e a simple windows share which Tiny PXE Server can manage for you.
\nSide note :
\n-I could make it work only with ubuntu 12.10, not 13.04.
\n-I could make it work only in plain DHCP mode, not proxydhcp mode.<\/p>\n

needed :
\n–ipxe<\/a>
\n–tiny pxe server<\/a>
\n–ubuntu<\/a><\/p>\n

1\/ open ubuntu.iso in winrar<\/h3>\n

(or any other iso reading capable tool)<\/p>\n

extract casper folder to x:\\pxe\\iso\\ubuntu.12.10 (or any path that suit you)<\/p>\n

 <\/p>\n

2\/use the below ipxe script :<\/h3>\n

#!ipxe
\nset boot-url http:\/\/${dhcp-server}
\nkernel ${boot-url}\/ubuntu.12.10\/casper\/vmlinuz showmounts toram root=\/dev\/cifs boot=casper netboot=cifs nfsroot=${cifs-server}\/pxe\/ubuntu.12.10 NFSOPTS=-ouser=username,pass=password,ro ip=dhcp ro
\ninitrd ${boot-url}\/ubuntu.12.10\/casper\/initrd.lz
\nboot<\/p>\n

In the script above, adapt the username and password.
\nname it ubuntu.ipxe and put it in x:\\pxe<\/p>\n

Note :
\nAbout that syntax, as there is a controversy, be aware that I did not make it up.
\nGoogle it and you’ll find tons of similar examples and\/or variants.
\nSee my latest post abou this here<\/a>.<\/em><\/p>\n

 <\/p>\n

3\/put ipxe-undionly.kpxe in x:\\pxe<\/h3>\n

 <\/p>\n

4\/modify config.ini with the following<\/h3>\n

(so that Tiny PXE Server will create a PXE share automatically for you pointing to your root folder) :
\n[dhcp]
\nsmb=1<\/p>\n

 <\/p>\n

5\/launch tiny pxe server with the following settings<\/h3>\n

(leave other settings untouched) :
\ntick \u00ab httpd \u00bb
\nboot filename = ipxe-undionly.kpxe (use the browse files and folders \u00ab \u2026 \u00bb button)
\ntick \u00ab filename if user-class=gPXE or iPXE \u00bb = http:\/\/${dhcp-server}\/ubuntu.ipxe
\npush the online button<\/p>\n

 <\/p>\n

6\/pxe boot your computer and here we go<\/h3>\n
