Has this computer ever booted? If so, when it booted, did it produce the blob-warning?
It is possible that the blob-warning is a red herring and the blob-warning message just happens to be the last message output before something went wrong.
I wouldn’t install anything at this stage. However whenever any computer has a problem booting, it is always a good idea to do a test boot from known good external media (such as a USB flash drive that you have booted from previously). That may then fault isolate.
