I plugged USB first then turned on system & went into BIOS to set hard drive order as
TSVJF(i think my pendrive's model)
because I have just one hard drive of 300GB
but same message 'boot error'
I found syslinux.cfg in USB.More explanation
Anything else expected.
$ find /pd -iname '*lin*'
you said related to smps.
i can just say that during bootup the LED of my pendrive glows and system has no UPS just direct connection to AC current.
Do you mean that I boot from hard drive & see output of dmesg.
If I do that let's say plug USB first then power the system.I get 'boot error' then press enter to get grub menu for my hard drive & get into ubuntu.
$dmesg | grep -i error
[ 39.831772] ACPI: Looking for DSDT in initramfs... error, file /DSDT.aml not found.
What do you say?
Since you said to try same USB again on a different computer.I did ( on dual core 2GB RAM,2.5GHz ) & it worked so I can conclude that there is a fault in my CPU.
root@lxuser-desktop:~# dosfsck -a /dev/sdb1
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
/dev/sdb1: 232 files, 22818/62493 clusters
The same USB did not work on another CPU of a friend of same model (i.e. core2duo 2GB RAM , 3GHz ).
What do you say ? Does core2duo stop booting from USB after few months.
