You are not alone, I have exactly the same error as you! I have posted the same question here and will be keeping an eye on your thread too. Heres hoping someone out there can solve our problem.
Good luck fella!

Immediately after the startup chime:
- key command-r and do not release the key until the Apple logo appears.
If the preparation or installation stage progressed as far as installation of the Lion Recovery OS, then command-r will start the Recovery OS and present Mac OS X Utilities.
If Mac OS X Utilities are offered, use Disk Utility. Copy the detail presented by Disk Utility, then use Recovery OS Safari to paste to this topic.

Same problem with my Mac Book Pro. Command R doesn't help. At installing Mac OSX Gets about 5 sec into time remaining 33 mins and then bar starts to turn yellow and then the error message. No way to revert to previous OS and won't install new OS. How do we recover?

Cmd R didn't work for me either. I'm currently doing an erase and install from my original OSX disks. It means I'll need to reinstall Snow Leopard too before I get to Lion but at least I should have a nice clean install. Looks like I'm in for a late night. Good luck guys.

Thank you. Please try the following:
- reset PRAM and NVRAM
- immediately after the chime that signals a successful reset, key alt/opion until the EFI boot options appear
- let us know whether your normal startup volume is amongst those boot options.

Here is what it reported.
Unused node is not erased (node=924)
Checking catalog file
Invalid node structure
The volume Macintosh HD could not be verified completely
Error: This disk needs to be repaired. ClickRepair Disk
Can't repair because Repair Disk is greyed out.

Thank you. Now:
- have handy your Snow Leopard DVD
- quit from Recovery OS Disk Utility
- quit from Recovery OS Mac OS X Utilities
- at the startup disk prompt, we hope to see your normal startup volume.
If (4) is true then you might simply carry on using Snow Leopard pending further investigation of what went wrong with the attempt to install.
We might find that the volume issues most recently described by Recovery OS Disk Utility are transient. (Without getting too technical: for a system started in a certain way, certain errors might be negligible.)
The surer approach, if you see your normal startup volume, will be to start instead from your Snow Leopard DVD and use its Utilties menu to run the older version of Disk Utility.
Please let us know what happens.
Looking ahead, after your normal Snow Leopard startup volume is verified …
At your leisure, and before your next attempt to use the installer for Lion, check the target volume for the presence of the following directory, at the root of the volume:
/Mac OS X Install Data
If you find a software distribution there, maybe as a .dmg, resist the temptation to use any such .dmg out of context.
More useful: the directory may contain the log(s) of one or both of the two stages of installation:
- post-preparation installation.
The logged data will be useful in any report to Apple.

I used the Leopard DVD Disk Utility to repair the HD and got this error.
Disk Utility stopped repairing "Machintosh HD" Disk utility can't repair this disk. Backup as many of your files as possible, reformat thr disk and restore your backed up files.
Guess that is the next action??
